The end of the NFL regular season means the beginning of the NFL firing and hiring season. Over the next few months, we will see major changes among NFL coaching staff and player rosters—especially with players, as a diminished salary cap on the horizon could mean more turnover than ever this year. But the player (and coach) turnover discussion is for another day. Here I’ll focus on the trickier process of change at the top of the football operation: the general manager. At least seven teams (Atlanta, Carolina, Denver, Detroit, Houston, Jacksonville and Washington) are now looking for a new general manager with perhaps more to come. These hires will set the direction of these franchises for, hopefully, years to come.
