I really hope people don't decide to smear the guy on the way out the door because he can't win basketball games. By all accounts, he's a great guy. And while some of the RUMORS of his conduct aren't necessarily professional, I don't think there's anything that says he's a bad human.
Even in the event they fire him for cause - that's obviously on him. And I suspect - again not based in fact but in a general pooling of things I've heard/observed over the years - that he likely would have this happen and not be privvy to it. He seems like a straight arrow, almost too straight for his own good. But he also doesn't seem to be a very conscientious manager and there's clearly issues of communication on multiple levels in the program between him, past coaches and players. So that's what i'd suspect/assume. He's still responsible - he's the head guy. But its not an implication on him as a person, but rather as a manager.
But if he DID know, man... what a killer.
