This is not an opinion on how things ended with Kevin Ollie or his ongoing litigation. I'd be shocked if he gets a head coaching job in the NBA. I'd even be surprised if he gets a head coaching job at a mid-major or better in college (after his show cause). It's not just that he flamed out at UConn and not even the violations (the NBA wouldn't care), it's how it went down and what he's done since. There were rumors of KO mailing it in, and he's done nothing since being terminated. He needs to earn his way back up.
Look at Jeff Capel. Ran into NCAA issues and poor performance after a hot start (similar to KO) and was terminated in March 2011. He joined Duke's staff in May 2011 and after moving up the bench, he got the Pitt job in 2018. Granted, he was able to get a gig at his alma mater, whereas Ollie was fired by his, but KO has done nothing in 2+ years, and doesn't even seem to be interested based on his actions and words. I have to think he could've gotten an assistant job in college or the NBA (more likely than college after the show cause).
