September 25th of 2016 was the last time Les Miles had a job. The day after losing to Auburn, Miles was relieved of his duties as head coach of LSU in the Fall of '16.
Since that time he's mostly stayed out of the limelight and coaching, well until now. Miles appears to have found his second love, acting. AL.com released a video this morning of Miles showing off his acting chops.
He needs some work, but he's no doubt got some time to improve his craft while away from coaching.
