Florida Atlantic head coach Lane Kiffin has had an interesting ride as a football coach.

Kiffin has been around the block a few times, and it seems every stop has had a bumpy ending. His most recent stop, offensive coordinator for Nick Saban and Alabama, ended abruptly just before the College Football Playoff Title Game.

Matt Hayes with Bleacher Report reports that things were especially testy at the end of Kiffin’s run with Alabama.

At one point during Kiffin’s last week in Tuscaloosa, an Alabama staffer says he was answering his phone on the field during practice, trying to assemble a staff and recruit for FAU while his current team was preparing for the College Football Playoff. He was showing up late to team meetings and missed the team bus after the CFP semifinal media day—at which he had told reporters he didn’t recall a time when Saban was happy with his play-calling; he only recalled “the ass chewings.”

At the end of the day, Saban eventually had enough of Kiffin’s antics.

“Nick was sick of all that nonsense, and that wasn’t the half of it,” says a former Alabama staffer. “It had been building for a while. The last thing Nick wants is for something like that to infiltrate his process. He won’t let that happen. One way or the other, Lane wasn’t coaching at Alabama after last season. Nick just cut it one game short.”

Another former coworker mentioned that he, and others, wanted to physically fight Kiffin towards the end of their time together.

“By the end of our time together, I wanted to physically beat his ass,” says one former coach who worked with Kiffin. “And I wasn’t the only one.”

One of his assistants from Tennessee claimed Kiffin’s style was “fast and loose” during his stay in Knoxville.

“He did a helluva job. Probably still his best coaching job,” says one of Kiffin’s assistants at Tennessee. “But he played fast and loose—there’s no doubt about that. Would something have come up eventually that could’ve ended it all? Probably.”

Despite everything that has happened surrounding Kiffin, Saban still praises his ability. Saban does believe that Kiffin must learn that coaching is about working with people.

“Lane is a very smart coach,” explained Saban. “He knows the game, but what Lane will figure out, what every coach eventually figures out, is it’s about people.”

Kiffin’s time with FAU will end smoother than his other stops. His head coaching career may depend on it.
