​The ​Kansas City Chiefs are already making changes to their coaching staff just two days removed from a heartbreaking AFC Championship loss to the ​New England Patriots

The team's biggest problem throughout the season was their defense and they will quickly work to address the issues on that side of the ball. The team has fired ​defensive coordinator Bob Sutton after a season in which the Chiefs' defense finish towards the bottom of league by most standards. 

Despite boasting one of the best offenses in the league, the ​Chiefs were plagued by their inability to make stops on defense, particularly against the pass. Their defense allowed 26.3 points per game and were the second-worst passing defense in football. 

Sutton's defensive unit wasn't able to contain the high-powered offenses the Chiefs' matched up against and they were defeated in the overtime drive against the Patriots as they failed to stop Tom Brady's aerial assault. 

Head coach Andy Reid gave a short statement after announcing that Sutton had been removed from his position. 

“Bob is a good football coach and a great person. He played an integral role in the success of our team over the last six seasons. I’ve said before that change can be a good thing, for both parties, and I believe that is the case here for the Chiefs and Bob. This was not an easy decision, but one I feel is in the best interest of the Kansas City Chiefs moving forward," Reid said via the Chiefs website. 

The Chiefs will now look to scoop up a new defensive coordinator in the open market this offseason as they have many questions to sort out on that side of the football.
