After defeating their rival, the Oakland Raiders 35–3 in Week 17, the Chiefs clinched their third consecutive division title and home-field advantage throughout the playoffs for the first time since 1997.[2]
In the playoffs, the Chiefs advanced to the AFC Championship Game for the first time since 1993 by defeating the Indianapolis Colts, 31–13 in the divisional round. This win ended the Chiefs' 6-game home playoff losing streak dating back to 1993. It was only the Chiefs' second win in their last 13 playoff games. In the AFC Championship Game, the Chiefs lost to the eventual Super Bowl champion New England Patriots, 37–31 in overtime. Two days after the loss, defensive coordinator Bob Sutton was fired following multiple NFL analysts criticizing his lack of adjustments in the AFC Championship Game, as well as other games throughout the season.[3]
