That's only because Mitch gave him a LIFETIME contract. So you're right, it doesn't matter what Cal does from here on out, he won't be fired. But if he doesn't at least get this team to a Final 4 with the National Player of the Year, there will be considerable heat on him from the fans and media.
So, will Cal's ENORMOUS ego allow him to stay at UK when he no longer can BS his way out of losing in the post season? Will he continue to hang onto a job when fans and followers of the program no longer look at him in high regard, but as a carpet bagger that has lost his golden touch?
After last season, Cal used up most of his equity from the first 6 seasons. It's been way too long since we got to a Final 4 for a coach that's paid what he is. But, if Cal wants to be stubborn, he can stay here and either fix the problems or end up being HATED by those that love the program.
