The National Football League (NFL) is a North American professional football league and the highest level of american football competition in the United States. The league consists of 32 teams that are divided between two conferences: the American Football Conference (AFC) and the National Football Conference (NFC). The NFL was formed in 1920 as the American Professional Football Association and adopted the name National Football League in 1922. In 1970 the league expanded when the, then American Football League, merged with the NFL bringing several new teams into the league. The NFL is one of the most popular sports leagues in the United States, and has the highest per-game attendance of any domestic professional sports league in the world, drawing over 67,591 spectators per game.

Early era

Further information: History of American football
NFL 1960

National Football League logo (1960–1969)

The American Professional Football Association was founded in 1920 at a Hupmobile dealership in Canton, Ohio. Legendary athlete Jim Thorpe was elected president. It was the first league of American Football in the United States for which players were paid a salary to participate. The group of eleven teams, all but one in the Midwest, was originally less a league than an agreement not to rob other teams' players. In the early years, APFA members continued to play non-APFA teams.

In 1921, the APFA began releasing official standings, and the following year, the group changed its name to the National Football League. However, the NFL was hardly a major league in the 1920s. Teams entered and left the league frequently. Franchises included such colorful representatives as the Providence Steam Roller, the Decatur Staleys, and the LaRue, Ohio Oorang Indians, an all-Native American outfit that also put on a performing dog show.

Yet as former college stars like Red Grange and Benny Friedman began to test the professional waters, the pro game slowly began to increase in its popularity. By 1934 all of the small-town teams, with the exception of the Green Bay Packers, had moved to or been replaced by teams in big cities. One factor in the league's rising popularity was the institution of an annual championship game in 1933.

1933 was also the year that black players disappeared from the NFL, just after the acceptance into the league of Boston Braves owner George Preston Marshall, who effectively dissuaded other NFL owners from employing black players until the mid-forties, and who kept blacks off his team (which eventually became the Washington Redskins) until he was forced to integrate by the Kennedy administration in 1962.[2]

By the end of World War II, pro football began to rival the college game for fans' attention. The spread of the T formation led to a faster-paced, higher-scoring game that attracted record numbers of fans. In 1945, the Cleveland Rams moved to Los Angeles, becoming the second big-league sports franchise on the West Coast (second to the Seattle Metropolitans in the PCHA). In 1950, the NFL accepted three teams from the defunct All-America Football Conference, expanding to thirteen clubs.

In the 1950s, pro football finally earned its place as a major sport. The NFL embraced television, giving Americans nationwide a chance to follow stars like Bobby Layne, Paul Hornung, Otto Graham, and Johnny Unitas. The 1958 NFL championship, played in Yankee Stadium (but blacked out by league policy in New York City) drew record TV viewership and made national celebrities out of Unitas and his Baltimore Colts teammates.

The rise of professional football was so fast that by the mid-1960s, it had surpassed baseball as Americans' favorite spectator sport in some surveys. When the NFL turned down Lamar Hunt's request to purchase either an existing or expansion NFL franchise, he formed the rival American Football League (AFL), in 1960. He encouraged, wheedled, and cajoled seven other like-minded men to form this new league. The group of the eight founders of the AFL teams was referred to as the "Foolish Club." One of them, fellow Texan Bud Adams of Houston, had likewise tried but failed to be granted an NFL franchise. Hunt's goal was to bring professional football to Texas and to acquire an NFL team for the Hunt family. The AFL filed an anti-trust lawsuit against the NFL in 1960, but this was dismissed in 1962.

The AFL introduced features that the NFL did not have, such as wider-open passing offenses, players' names on their jerseys, and an official clock visible to fans so that they knew the time remaining in a period (the NFL kept time by a game referee's watch, and only periodically announced the actual time). The newer league also secured itself financially after it established the precedents for gate and television revenue sharing between all of its teams, and network television broadcasts of all of its games. While the NFL virtually ignored small and historically black colleges as a source of player talent, the AFL actively recruited from such schools and AFL teams installed blacks at positions from which they were tacitly excluded in the NFL, such as quarterback[1] and middle linebacker[2].

One of the seminal civil-rights actions of the 1960s was the boycott by AFL players of the 1964 (January 1965) AFL All-Star Game scheduled for New Orleans, after black players were refused service from cabbies and hotel staff there. The game was successfully moved to Houston. Even though they were AFL players who had accomplished this action, at the Pro Football Hall of Fame in Canton, Ohio, there is a small exhibit detailing the integration of professional football. A brief video clip addresses the boycott and credits the players (and implicitly the National Football League, although at the time it had no involvement with the players) with changing two racial laws in New Orleans.

The AFL also forced the NFL to expand: The Dallas Cowboys were created to counter Hunt's AFL Dallas Texans franchise. The Texans moved the franchise to Kansas City as the Chiefs in 1963; the Minnesota Vikings were the NFL franchise given to Max Winter for abandoning the AFL; and the Atlanta Falcons franchise went to Rankin Smith to dissuade him from purchasing the AFL's Miami Dolphins.

The ensuing costly war for players between the NFL and AFL almost derailed the sport's ascent. By 1966, the leagues agreed to merge as of the 1970 season. The ten AFL teams joined three existing NFL teams to form the NFL's American Football Conference. The remaining thirteen NFL teams became the National Football Conference. Another result of the merger was the creation of an AFL-NFL Championship game that for four years determined the so-called "World Championship of Professional Football". After the merger, the then-renamed Super Bowl became the NFL's championship game.

Modern era

NFL 1970

National Football League logo (1970–2007)

In the 1970s and 1980s, the NFL solidified its dominance as America's top spectator sport and its important role in American culture. The Super Bowl became an unofficial national holiday and the top-rated TV program most years. Monday Night Football, which first aired in 1970, brought in high ratings by mixing sports and entertainment. Rule changes in the late 1970s ensured a fast-paced game with lots of passing to attract the casual fan.

The founding of the United States Football League in the early 1980s was the biggest challenge to the NFL in the post-merger era. The USFL was a well-financed competitor with big-name players and a national television contract. However, the USFL failed to make money and folded after three years. The USFL filed a successful anti-trust lawsuit against the NFL, but the remedies were minimal.

In recent years, the NFL has expanded into new markets and ventures. In 1986, the league began holding a series of pre-season exhibition games, called American Bowls, held at international sites outside the United States. Then in 1991, the league formed the World League of American Football, later known as NFL Europe and still later as NFL Europa, a developmental league that had teams in Germany and the Netherlands when the NFL shut it down in June 2007. The league played a regular-season NFL game in Mexico City in 2005 and intends to play more such games in other countries. In 2003, the NFL launched its own cable-television channel, NFL Network.

The NFL proper has announced that this season, a regular season game between the Miami Dolphins and the New York Giants will be held outside the borders of the United States.

On August 31, a story in USA Today unveiled the first changes to the league's shield logo since 1980, which will take effect with the 2008 season [3]. The redesign reduces the number of stars in the logo from 25 (which were found not to have a meaning beyond decorative) to eight (for each of the league's divisions), the logo's football repositioned in the manner of the Vince Lombardi Trophy, and the NFL letters in a straight serifed font (which resembles the current typeface used in other NFL logos). The redesign was created with television and digital media, along with clothing in mind.

Franchise relocations and mergers

For more details on this topic, see NFL franchise moves and mergers.

In the early years, the league was not stable and teams moved frequently. Franchise mergers were popular during World War II in response to the scarcity of players.

Franchise moves became far more controversial in the late 20th century when a vastly more popular NFL, free from financial instability, allowed many franchises to abandon long-held strongholds for perceived financially greener pastures. While owners invariably cited financial difficulties as the primary factor in such moves, many fans bitterly disputed these contentions, especially in Cleveland (the Rams and the Browns), Baltimore (the Colts), Houston (the Oilers) and St. Louis (the Cardinals), each of which eventually received teams some years after their original franchises left (the Browns, Ravens, Texans and the Rams respectively). However, Los Angeles, the second-largest media market in the United States, has not had an NFL team since 1994 after both the Raiders and the Rams relocated elsewhere.

Additionally, with the increasing suburbanization of the U.S., the building of new stadiums and other team facilities in the suburbs instead of the central city became popular from the 1970s on, though at the turn of the millennium a reverse shift back to the central city became somewhat evident.

Season structure

As of 2021, The NFL season features:

  • A 3-game (or 4-game due to the Pro Football Hall of Fame Game) exhibition season (or preseason) running from early August to early September
  • A 17-game regular season running from September to early January
  • A team does not win a championship or any trophy for having the best record during the regular season, but the league does recognize a champion for each of the 8 divisions.
  • A 14-team playoff tournament beginning in January culminating in the Super Bowl on the second Sunday of February.
  • The winner of the Super Bowl is the NFL Champion.

Exhibition season

  • Main article: National Football League exhibition season

Following mini-camps in the spring and officially recognized Training Camp in July-August, NFL teams typically play four exhibition games (referred to by the NFL as "pre-season games"; the league discourages the use of the term "exhibition game") from early August through early September. One "featured" pre-season game, the Pro Football Hall of Fame Game, does not count toward the normal allotment of four games, so the two teams playing in that game each end up playing five exhibition games.

The games are useful for new players that are not used to playing in front of very large crowds. Management often uses the games to evaluate newly signed players. Veteran starters will generally play only for about a quarter of each game so they can avoid injury.


Current NFL playoff tree

An example of the NFL playoff tree. This playoff system was used from the 1990 NFL playoffs to the end of the 2019 playoffs.

Following the conclusion of the regular season, the NFL Playoffs, a 14-team single-elimination tournament, is then held. Seven teams are selected from each conference: the winners of each of the four divisions as well as three wild card teams (the three remaining teams with the best overall record, with tiebreakers in the event of two or more teams having the same record). These teams are seeded according to overall record and tiebreakers, with the division champions always ranking higher than the wild card teams. The top team (seeded one) from each conference are awarded a bye week, while the remaining six teams (seeded 2–7) from each conference compete in the first round of the playoffs, the Wild Card round, with the 2-seed competing against the 7-seed, the 3-seed competing against the 6-seed and the 4-seed competing against the 5-seed. The winners of the Wild Card round advance to the Divisional Round, which matches the lower seeded team against the 1-seed and the two remaining teams against each other. The winners of those games then compete in the Conference Championships, with the higher remaining seed hosting the lower remaining seed. The AFC and NFC champions then compete in the Super Bowl to determine the league champion.

The only other postseason event hosted by the NFL is the Pro Bowl, the league's all-star game. Since 2009, the Pro Bowl has been held the week before the Super Bowl; in previous years, the game was held the week following the Super Bowl, but in an effort to boost ratings, the game was moved to the week before. Because of this, players from the teams participating in the Super Bowl are exempt from participating in the game. The Pro Bowl is not considered as competitive as a regular-season game because the biggest concern of teams is to avoid injuries to the players.



For more details on this topic, see NFL on television.

The television rights to the NFL are the most lucrative and expensive rights not only of any American sport, but of any American entertainment property. With the fragmentation of audiences due to the increased specialization of broadcast and cable TV networks, sports remain one of the few entertainment properties that not only can guarantee a large and diversified audience, but an audience that will watch in real time.

Annually, the Super Bowl often ranks among the most watched shows of the year. Four of Nielsen Media Research's top ten programs are Super Bowls.[4] Networks have purchased a share of the broadcasting rights to the NFL as a means of raising the entire network's profile.[5]

Under the current television contracts, which began during the 2006 season, regular season games are broadcast on five networks: CBS, FOX, NBC, ESPN, and the NFL Network. Regionally shown games are broadcast on Sundays on CBS and FOX, carrying the AFC and NFC teams respectively (the traveling team deciding the broadcast station in the event of inter-Conference games). These games generally air at 1:00 p.m. ET and 4:00 p.m. or 4:15 p.m. ET. Nationally televised games include Sunday night games (shown on NBC), Monday night games (shown on ESPN), the Thursday night NFL Kickoff Game, the annual Dallas Cowboys and Detroit Lions Thanksgiving Day games, and, as of 2006, select Thursday and Saturday games on the NFL network, a wholly owned subsidiary of the National Football League.[6][7]

Additionally, satellite broadcast company DirecTV offers NFL Sunday Ticket, a subscription based package, that allows most Sunday daytime regional games to be watched.[8][9] This package is exclusive to DirecTV in the USA. In Canada, NFL Sunday Ticket is available on a per-provider distribution deal on both cable and satellite.


Each NFL team has its own radio network and employs its announcers. Nationally, the NFL is heard on the Westwood One Radio Network, Sports USA Radio Network and in Spanish on Univision Radio and the United Stations Radio Network. Westwood One carries Sunday and Monday Night Football, all Thursday games, two Sunday afternoon contests and all post-season games, including the Pro Bowl. Sports USA Radio broadcasts two Sunday afternoon games every Sunday during the regular season.[6]

The NFL also has a contract with Sirius Satellite Radio, which provides news, analysis, commentary and game coverage for all games, as well as comprehensive coverage of the draft and off-season on its own channel, Sirius NFL Radio.[6]

Internet radio broadcasts of all NFL games are managed through FieldPass, a subscription service. Radio stations are, by rule, prohibited from streaming the games for free from their Web sites; however, there are numerous stations that break this rule. The NFL on Westwood One and the NFL on Sports USA Radio are not available on FieldPass.

Player contracts and compensation

Most of this section is no longer accurate, pending resolution of the 2011 owner's lockout.

NFL players are all members of a union, called the National Football League Players Association (NFLPA). The NFLPA negotiates the general minimum contract for all players in the league. This contract is called the Collective Bargaining Agreement (CBA), and it is the central document that governs the negotiation of individual player contracts for all of the league's players. The current CBA has been in place since 1993, and amended in 1998 and again in 2006. The NFL has not had any labor-related work stoppages since the 1987 season, which is much longer than Major League Baseball, the NBA or the NHL. The most recent CBA was due to expire at the end of the 2012 season, bur was voided by the owners in early 2011.[10]

Players are tiered into three different levels with regards to their rights to negotiate for contracts:

  • Players that have been drafted (see below), and have not yet played in their first year, may only negotiate with the team that drafted them.[10] If terms cannot be agreed upon, the players only recourse is to refuse to play ("sit out") until terms can be reached. Players often use the threat of sitting out as a means to force the hands of the teams that drafted them. For example, John Elway was drafted by the Baltimore Colts in 1983 but refused to play for them. He had a fallback option of baseball, as he had played in the New York Yankees organization for two summers while at Stanford. The Colts traded his rights to the Denver Broncos and Elway agreed to play.[11] Bo Jackson sat out an entire year in 1986, choosing to play baseball in the Kansas City Royals organization (and ultimately for the Royals themselves) rather than play for the Tampa Bay Buccaneers who had drafted him. He reentered the draft the following year, and was drafted and subsequently signed with the Los Angeles Raiders.[12]
  • Players that have played between 3–5 full seasons in the league, and whose contract has expired are considered "Restricted Free Agents" (see below). They have limited rights to negotiate with any club.[10]
  • Players that have played 5 or more full seasons in the league, and whose contract has expired, are considered "Unrestricted Free Agents"(see below) and have unlimited rights to negotiate with any club. Teams may name a single player in any given year as a "Franchise Player"(see below), which eliminates much of that players negotiation rights. This is a limited right of the team, however, and affects only a small handful of players each year.[10]

Among the items covered in the CBA are:

  • Salary Cap
  • The annual collegiate draft
  • Rules regarding "free agency"
  • Waiver rules


A player's salary, as defined by the CBA, includes any "compensation in money, property, investments, loans or anything else of value to which an NFL player may be awarded" excluding such benefits as insurance and pension. A salary can include an annual pay and a one-time "signing bonus" which is paid in full when the player signs his contract. For the purposes of the salary cap (see below) the signing bonus is prorated over the life of the contract rather than to the year in which the signing bonus is paid.[13]

Player contracts are not guaranteed; teams are only required to pay on the contract as long as the player remains a member of the team. If the player is cut, or quits, for any reason, the balance of the contract is voided and the player receives no further compensation.[14]

Among other things, the CBA establishes a minimum salary for its players,[14] which is stepped-up as a player's years of experience increase. Players and their agents may negotiate with clubs for higher salaries, and frequently do. As of the 2005 NFL season, the highest paid player was Atlanta Falcons quarterback Michael Vick, whose "cap value" was slightly under $8 million.[15] The overall value of his contract is 10 years at $130 million, averaging $13 million a year, including signing bonuses and annual salary[16].

Salary cap

The salary cap is defined as the maximum amount that a team may spend on player compensation, (see above) for all of its players combined. Unlike other leagues, for example the NBA (which permits certain exemptions) or Major League Baseball (which has a "soft cap" enforced by "luxury taxes"), the NFL has a "hard cap": an amount no team under any circumstances may exceed.

The NFL salary cap is calculated by the current CBA to be 59.5% of the total projected league revenue for the upcoming year. This number, divided by the number of teams, determines an individual teams maximum salary cap. For 2006, this is approximately $102 million per team. For 2007, it is projected that this will rise to $109 million.[14]

Teams and players often find creative ways to fit salaries under the salary cap. Early in the salary cap era, "signing bonuses" were used to give players a large chunk of money up front, and thus not count in the salary for the bulk of the contract. This led to a rule whereby all signing bonus are pro-rated equally for each year of the contract. Thus a player who receives a $10 million dollar signing bonus for a 5 year contract would count $2 million per year for the life of the contract, even though the full $10 million was paid up front during the first year of the contract. Also, if a team cuts any player, the signing bonus ceases to be pro-rated, and the entire balance of the bonus counts against the cap in the upcoming season. This is not true of a player's salary which terminates when the player is cut.[14]

Player contracts tend to be "back-loaded". This means that the contract is not divided equally among the time period it covers. Instead, the player earns progressively more and more each year. For instance, a player signing a 4-year deal worth $10 million may get paid $1 million the first year, $2 million the second year, $3 million the third year, and $4 million the fourth year. If a team cuts a player after the first year, the final 3 years do not count against the cap. However, the balance of any signing bonus still counts against the team that cut the player, and it counts in full the year after the player is cut.[14]

Demographics of the NFL

As of the beginning of the 2012 season, the players of the NFL were as follows:

  • African American: 1804 or 65.8%,
  • White American: 820 or 29.6%,
  • Other Race: 136 or 4.6%.


The NFL Draft

For more details on this topic, see NFL Draft.

Every year during April, each NFL franchise seeks to add new players to its roster through a collegiate draft known as "the NFL Annual Player Selection Meeting", which is more commonly known as the NFL Draft.

Teams are ranked in inverse order based on the previous season's record, with the worst record picking first, and the second worst picking second and so on. The draft proceeds for 7 rounds. Rounds 1–3 are run on Saturday of draft weekend, rounds 4–7 are run on Sunday. Teams are given a limited amount of time to make their picks.[18] If the pick is not made in the allotted time, subsequent teams in the draft may draft before them. This happened in 2003 to the Minnesota Vikings.[19]

Teams have the option of trading away their picks to other teams for different picks, players, cash, or a combination thereof. While player-for-player trades are rare during the rest of the year (especially in comparison to the other major league sports), trades are far more common on draft day. In 1989, in arguably the most famous draft day trade ever, the Dallas Cowboys traded running back Herschel Walker to the Minnesota Vikings for five veteran players and six draft picks over 3 years. The Cowboys would use these picks to leverage trades for additional draft picks and veteran players. As a direct result of this trade, they would draft many of the stars that would help them win 3 Super Bowls in the 1990s, including Emmitt Smith, Russell Maryland and Darren Woodson.[20]

The first pick in the draft is often taken to be the best overall player in the rookie class. This may or may not be true, since teams often select players based more on needs than on overall skill. Plus, comparing players at different positions is difficult to do. Still, it is considered a great honor to be a first-round pick, and a greater honor to be the first overall pick. The very last pick in the draft is known as Mr. Irrelevant, and is the subject of a dinner in his honor in Newport Beach, California.

Drafted players may only negotiate with the team that drafted them (or to another team if their rights were traded away). The drafting team has one year to sign the player. If they do not do so, the player may reenter the draft and can be drafted by another team. Bo Jackson famously sat out a season in this way.[12]

Free agency

For more details on this topic, see Free Agent#NFL Usage.


As defined by the CBA, a free agent is any player who is not under contract to any team and thus has fully free rights to negotiate with any other team for new contract terms.[10][21] Free agents are classified into two categories: restricted and unrestricted. Furthermore, a team may "tag" a player as a franchise or transition, which places additional restrictions on that player's ability to negotiate. However, the ability to "tag" is quite limited, and only affects a handful of players each year.

Free agency in the NFL began with a limited free agency system known as "Plan B Free Agency", which was in effect between the 1989 and 1992 seasons. Beginning with the 1993 season, "Plan A Free Agency" went into effect, which is the system which remains in the NFL today.

Restricted free agent

A player who has 3-5 years of experience is eligible for restricted free agency, whereby his current team has the chance to retain rights to this player by matching the highest offer any other NFL franchise might make to that player. The club can either block a signing or, in essence, force a trade by offering a salary over a certain threshold. In 2006, these thresholds were as follows:

  • If a club tenders an offer of $685,000 per year for a three year veteran, and $725,000 for a four year veteran, the player's current team has "right of first refusal" over the contract at those terms, and may sign the player at those terms.
  • If a club tenders an offer of $712,000 or 110% (whichever is greater) of the previous year's salary, then the current club has both "right of first refusal" and rights to a draft pick from the same round (or better) from the signing club. Essentially, this means that the new club must forfeit the draft pick to the old club if they wish to sign the player under these terms.
  • If a club tenders an offer of $1.552 million or 110% (whichever is greater) of the previous year's salary, then the current club has both "right of first refusal"; and rights to the first round draft pick from the signing club.[21]

Unrestricted free agent

A player who has 5 or more years of experience is eligible for unrestricted free agency, whereby his current team has no guaranteed right to match outside offers to that player. This means that players in this category have unlimited rights to negotiate any terms with any team.[21]

Franchise tag

The franchise tag is a designation given to a player by a franchise that guarantees that player a contract the average of the five highest-paid players of that same position in the entire league, or 120% of the player's previous year's salary (whichever is greater) in return for retaining rights to that player for one year. An NFL franchise may only designate one player a year as having the franchise tag, and may designate the same player for consecutive years. This has caused some tension between some NFL franchise designees and their respective teams due to the fact that a player designated as a franchise player precludes that player from pursuing large signing bonuses that are common in unrestricted free agency, and also prevents a player from leaving the team, especially when the reasons for leaving are not necessarily financial. A team may, at their discretion, allow the franchise player to negotiate with other clubs, but if they sign with another club, the first club is entitled to two first round draft picks in compensation.[21]

Steroid policy

The NFL steroid policy has been acclaimed by some [3] and criticized by others[4], but the policy is the longest running in professional sports, beginning in 1987. [5] The current steroid policy of the NFL suspends players without pay who test positive for banned substances as it has since 1989: four games for the first offense (a quarter of the regular season), eight games for a second offense (half of the regular season), and 12 months for a third offense. [6] The suspended games may be either regular season games or playoff games. [7]

In comparison to the steroid policies of Major League Baseball and the National Hockey League, the NFL has long been the most strict. While recently MLB and the NHL decided to permanently ban athletes for a third offense, they have long been resistant to such measures, and random testing is in its infancy. [8] [9]

Since the NFL started random, year-round tests and suspending players for performance enhancing drugs it has caught many more players using drugs. By April 2005, 111 NFL players had tested positive for performance enhancing drugs, and of those 111, the NFL suspended 54. Only two NFL players have ever tested positive more than once, and they both retired. [10]

A new rule has been put into effect due to Shawne Merriman. Starting the 2007–2008 season, the new rule prohibits any player caught using performance enhancing drugs from being able to play in the Pro Bowl that year.

Current NFL teams

Template:NFL Labelled Map There are 32 NFL teams. Each club is allowed a maximum of 55 players, though nearly every team keeps only 53 on their final roster in case of injury, during the regular season. Unlike Major League Baseball, Major League Soccer, the National Basketball Association and the National Hockey League, the league has no teams in Canada largely because of the historical existence of the Canadian Football League.

Most major metropolitan areas in the United States have an NFL franchise; the notable exception is the Los Angeles area, from which both the Raiders and Rams relocated following the 1994 season. The NFL is able to utilize the possible relocation of a franchise to Los Angeles as leverage, for example when trying to persuade local governments to contribute to the cost of new stadiums for its other franchises.[22] The Washington Redskins are the most lucrative sports team of all U.S. professional teams, valued at approximately $1.4 billion.[23]

Since the 2002 season, the teams have been aligned as follows:[24]

Video games

Electronic Arts publishes an NFL video game for current video game consoles and for PCs each year, called Madden NFL, being named after former coach and current football commentator John Madden, who comments on the game along with Al Michaels. Prior to the 2005–2006 football season, other NFL games were produced by competing video game publishers, such as 2K Games and Midway Games. However, in December 2004, Electronic Arts signed a five-year exclusive agreement with the NFL, meaning only Electronic Arts will be permitted to publish games featuring NFL team and player names. This prompted video game developer Midway Games to release a game in 2005 called Blitz: The League, with fictitious teams such as the "Washington Redhawks", and make references to NFL players such as the Washington Redhawks left-handed QB "Ron Mexico", alluding to Michael Vick (at the time playing for the Atlanta Falcons), who allegedly used the alias at a walk-in clinic.

Uniform numbers

In the NFL, players wear uniform numbers based on the position they play. The current system was instituted into the league on April 21, 2021, when uniform numbers allowed players to wear any number except for quarterbacks, punters, kickers, and linemen (offensive, defensive). Since that date, players are invariably assigned numbers within the following ranges, based on their primary position:

  • Quarterbacks, placekickers and punters: 1–19
  • Wide receivers, running backs, and tight ends: 1-49 and 80-89
  • Defensive backs: 1–49
  • Offensive linemen: 50–79
  • Linebackers: 1–59 and 90–99
  • Defensive linemen: 50–79 and 90–99

Prior to 2004, wide receivers were allowed to only wear numbers 80–89.[26] The NFL changed the rule that year to allow wide receivers to wear numbers 10–19 to allow for the increased number of players at wide receiver and tight end coming into the league. Prior to that, players were only allowed to wear non-standard numbers if their team had run out of numbers within the prescribed number range. Perhaps most familiar to fans, Keyshawn Johnson began wearing number 19 in 1996 because the New York Jets had run out of numbers in the 80s.

Occasionally, players will petition the NFL to allow them to wear a number that is not in line with the numbering system. Brad Van Pelt, a linebacker who entered the NFL in 1973 with the New York Giants, wore number 10 during his 11 seasons with the club, despite not being covered by the grandfather clause. In 2006, New Orleans Saints running back Reggie Bush petitioned the NFL to let him keep the number 5 which he used at USC. His request was later denied.[27] Former Seattle Seahawks standout Brian Bosworth attempted such a petition in 1987 (to wear his collegiate number of 44 at the linebacker position), also without success. The Seahawks attempted to get around the rule by listing Bosworth as a safety, but after he wore number 44 for a game against the Kansas City Chiefs, the NFL ruled Bosworth would have to switch back to his original number, 55.

It should be noted that this NFL numbering system is based on a player's primary position. Any player wearing any number may play at any position on the field at any time (though players wearing numbers 50–79 must let the referee know that they are playing out of position by reporting as an "ineligible number in an eligible position"). Normally, only players on offense with eligible numbers are permitted to touch the ball by taking a snap from center, receiving a hand-off or catching a pass. It is not uncommon for running backs to line up at wide receiver on certain plays, or to have a large lineman play at fullback or tight end in short yardage situations. Also, in preseason games, when teams have expanded rosters, players may wear numbers that are outside of the above rules. When the final 53-player roster is established, they are reissued numbers within the above guidelines.
