If he doesn't do his job, which includes recruiting, that might be grounds for firing for cause. His contract might be ironclad though, so maybe only moral turpitude could get him fired without guaranteed money. Certainly Nepotism/self dealing scholarships and playing time to his own kids was never problematic.
His recent recruits are more athletic/African American in composition than past classes. However they probably lack basketball skills like shooting, ball handling, understanding concepts on defense, etc. I wouldn't mind seeing what Tadjo could do even if he does suck, because at least he has upside.
Fran could leave with a solid legacy. Accept a reduced buyout, shape up this current year's team, and move on. Ceremony to honor him at last home game, free tickets to an NCAA Sweet16, Elite8, etc near the bench so he can get his first experience in his long career.
