2015 Kansas City Chiefs

The  Kansas City Chiefs season was the franchise's 46th season in the National Football League, the 56th overall and the third under the head coach/general manager tandem of Andy Reid and John Dorsey. The Chiefs went through a poor start in their first 6 games as they were 1–5, and lost their star running back, Jamaal Charles due to a torn ACL in his right knee during a 18–17 Week 5 loss at home against the Chicago Bears. In week 16, after their 9th consecutive victory and the Baltimore Ravens defeating the Pittsburgh Steelers, the Chiefs clinched a playoff berth, their 2nd in 3 years. They are the first team since the 1970 Cincinnati Bengals to start the season 1–5 and qualify for the playoffs. They also set the franchise record for the most consecutive victories, winning 11 in a row. In their wildcard matchup, the Chiefs played the Houston Texans. The Chiefs defeated the Texans 30–0 to earn their first playoff win in 22 years. The following week, they were defeated by the New England Patriots in the Divisional round by a score of 27–20.

AFC Wild Card Playoffs: at (#4) Houston Texans
The Texans, who won the weak AFC South division with a 9-7 record, were completley crushed by the Chiefs. The Chiefs made postseason history as the first ever team to score a kick return touchdown in the opening play of the playoffs, when Knile Davis returned the opening kick 106 yards for a touchdown. After that, the game started to slow down, 3 & out Texans, 3 & out Chiefs, followed by a string of turnovers, Eric Berry's interception of Brian Hoyer, Brian Cushing's interception of Alex Smith 2 plays later, and a Hoyer fumble recovered by Dontari Poe on the ensuing drive. The Chiefs manage a field goal on the drive, and although the team is able to get to the 2 yard line, a negative run by J.J. Watt and another interception by Hoyer ended the Texan's closest chance at scoring in the entire game. Although the Texans defense forced a 3-and-out, Hoyer throws his third interception to Marcus Peters on the 2nd play of their drive.

AFC Divisional Playoffs: at (#2) New England Patriots
The Chiefs, who had won 11 straight, travelled to Gillete Stadium to face the Patriots, who had advanced to the AFC Championship for the last 5 years. The Patriots scored first blood with a Rob Gronkowski touchdown catch, followed by a Cairo Santos field goal for Kansas City. The pattern was duplicated in the 2nd quarter, with Tom Brady rushing for a score before Santos kicked another field goal. In the 3rd quarter, after Gronkowski scored his second TD, Alex Smith threw his first to Albert Wilson. The Patriots responded with 2 fourth quarter field goals to make the score 27-13 with 10:20 left. Although the Chiefs go on a touchdown drive late in the game, the drive took up over 5 minutes, and the Chiefs had to force a 3 and out (with 3 timeouts) to have a chance. On 2nd down, when Brady threw the ball instead of running it to waste time, the ball was batted and miraculously caught by Julian Edelman for a 1st down, ending the game.
