A general manager (GM) in American football is a team executive who is typically the head of football operations, which includes leading the scouting department and being responsible for handling free agent transactions and contract negotiations with players and coaches. Under such a model, the GM reports directly to the owner or team president. However, some team owners serve as their own GM or employ one who acts in a supporting role to the head coach. Al Davis of the Oakland Raiders was an example of an owner who also served as GM, while Bill Belichick is an example of a head coach having de facto GM responsibilities during his tenure with the New England Patriots.
