For the Chicago Bears, a major question that surrounds the team in 2021 is what the defense will look like.
For the third time in four seasons, head coach Matt Nagy is set to have a different defensive coordinator. In 2018, Nagy stuck with Vic Fangio. 2019 and 2020 provided the opportunity for Nagy to work with veteran Chuck Pagano. Now, heading into 2021, Nagy has another defensive coordinator, with Sean Desai taking over the reigns.
