The biggest problem is that the stuff Pastner is terrible at are core personality traits that are very unlikely to change. He cannot relate to players, alienates them and cannot motivate them. He's awful at the day to day personal interactions that are the core of being a college basketball coach.
There's a reason the die hard basketball fans HATE this hire (Red(!) was campaigning to get people to call into try and have the contract blocked ... he's not an irrational person, he knows his stuff). This stuff isn't a secret by the way, it's quite well known around the basketball community - and it will have (and already has had) an impact on his ability to recruit. The words gets around - guys talk to their old AAU coaches, etc ...
