The 1971 Dallas Cowboys season was their 12th in the NFL. The club led the NFL with 406 points scored. Their defense allowed 222 points. For the sixth consecutive seasons, the Cowboys had a first place finish. The Cowboys made it to their second consecutive Super Bowl and beat the Miami Dolphins to capture their first Super Bowl Championship. They were the first team from the NFC East Division to win the Super Bowl.
The Cowboys entered the season still having the reputation of "not being able to win the big games" and "next year's champion". The Super Bowl V loss added more fuel to that widely held view. As in the previous season, Dallas had a quarterback controversy as Staubach and Craig Morton alternated as starting quarterback (in a loss to the Bears in game 7, Morton and Staubach alternated plays). The Cowboys were 4-3 at the season midpoint. But after head coach Tom Landry settled on Staubach, the Cowboys won their last seven regular season games to finish with an 11-3 record.
Staubach finished the regular season as the NFL's top rated passer (101.8) by throwing for 1,882 yards, 15 touchdowns, and only 4 interceptions. He was also a terrific rusher, gaining 343 yards and 2 touchdowns on 41 carries. Dallas also had an outstanding trio of running backs, Walt Garrison, Duane Thomas, and Calvin Hill, who rushed for a combined total of 1,690 yards and 14 touchdowns during the season. Garrison led the team in receptions during the season. (Thomas, upset that the Cowboys would not renegotiate his contract after his excellent rookie year, had stopped talking to the press and to almost everyone on the team). Wide Receivers Bob Hayes and Lance Alworth also provided a deep threat, catching a combined total of 69 passes for 1,327 yards and 10 touchdowns. The offensive line, anchored by all-pro tackle Rayfield Wright, Pro BowlersJohn Niland and Ralph Neely, and future hall of famerForrest Gregg, was also a primary reason for their success on offense. (Neely had broken his leg in November in a dirt-bike accident, and was replaced first by Gregg and then by Tony Liscio, who came out of retirement.)
The Dallas defense (nicknamed the "Doomsday Defense") had given up only one touchdown in the last 25 quarters prior to the Super Bowl. Their defensive line was anchored by Pro Bowl defensive tackle Bob Lilly, who excelled at pressuring quarterbacks and breaking up running plays. Dallas also had an outstanding trio of linebackers: Pro Bowler Chuck Howley, who recorded 5 interceptions and returned them for 122 yards; Dave Edwards 2 interceptions; and Lee Roy Jordan, who recorded 2 interceptions. The Cowboys secondary was led by 2 future hall of fame cornerbacks Herb Adderley (6 interceptions for 182 return yards) and Mel Renfro (4 interceptions for 11 yards). Safeties Cliff Harris and Pro Bowler Cornell Green also combined for 4 interceptions.
September 26, 1971 - Herb Adderley became the first Cowboy to have three interceptions in one game.
The Cowboys earned their first win on Monday Night Football by defeating the New York Giants 20-13.
