The Senior Bowl is home to a one-of-a-kind NFL Convention. In addition to the two NFL coaching staffs who coach the two Senior Bowl teams each year, over 700 NFL general managers, head coaches, assistant coaches, personnel directors, scouts and other front office personnel from the 32 NFL teams annually attend Senior Bowl Week in Mobile.
Coaching staffs for the game each year are selected by the NFL office. In addition to the coaches, each NFL team chosen by the league to coach the Senior Bowl teams also brings its training, video and equipment staffs to the contest to work with the Senior Bowl players and maximize the many benefits that the players will receive by playing in the contest.
