Pruitt is toxic and I'll be shocked if he doesn't get a show-cause order, probably at least five years. If he can't beg another NFL job, maybe he can go work for Jeff Fisher in the new USFL or something. Personally, I think the best fate for him would be permanent exile in Antarctica.
As for Derek Dooley, best of luck to him. He's not a bad guy, he was just over his head when he came to UT. He did the best he could. Might have lasted longer if he'd hired anyone other than Sal Sunseri to run his defense in 2012.
