  2019: First Super Bowl in 50 years
  Heading into the 2019 offseason, the Chiefs had many key players that they cut, traded, or allowed to become free agents. Some of these players included Dee Ford (traded after being franchise tagged), Mitch Morse, Chris Conley, Allen Bailey, Justin Houston, Eric Berry, and more. The Chiefs also had to find a new defensive coordinator after the firing of Bob Sutton following the collapse against New England in the AFC Championship game. The Chiefs would hire Steve Spagnuolo as their defensive coordinator on January 24, 2019.
  Kansas City enjoyed a 4–0 start before losing to the Indianapolis Colts and Houston Texans. Patrick Mahomes suffered a dislocated kneecap during the next game, a win over the rival Denver Broncos, missing the next two weeks. After an upset loss to the Tennessee Titans, the Chiefs would win their remaining games, including a Monday night game against the Los Angeles Chargers in Mexico City and a 23–16 win over the defending Super Bowl champions New England Patriots in Foxboro, to finish the season at 12–4, clinching the AFC West title and a first-round bye in the playoffs for the second consecutive season.
