In January 2017, just days before Alabama played Clemson for the national championship, Crimson Tide coach Nick Saban essentially fired his offensive coordinator, Lane Kiffin.
Officially it was because Kiffin's acceptance of the Florida Atlantic head coaching job had caused "distractions."
Really though, Kiffin had so worn out his welcome that Saban, a man who despises any disruption to pretty much anything, was willing to dump his playcaller before the biggest game of the season. (Alabama would lose to Clemson, although Saban, of course, said Kiffin's departure played no role.
