Between Illinois' firing of Tim Beckman a week before the 2015 season began in August and its removal last Saturday of his replacement, Bill Cubit -- a week before the scheduled start of spring practice - it was a busy season of coaching upheaval across the FBS.
Twenty-eight programs made changes at the top, including 13 of the 65 Power-5 programs with the last one being the Illini hiring former Tampa Bay Buccaneers and Chicago Bears coach Lovie Smith on Monday. Every major conference experienced at least one change, though it was a relatively quiet year in the Big 12 and Pac-12.
