As for Cuonzo being to blame for the player's current attitude, I am sure he did not help matters.
But based on statements by McRae and Maymon after the tourney run, I think the players got plenty pissed all on their own, and I don't blame them a bit for it.
A good coach, mentor, and role model has his guys more mentally tough than that, and only a horrible one actually uses that mental weakness to deliberately poison a team against its university and fanbase. Cuonzo is 100% to blame.
This is big-time athletics, and fans are harsh. And you know what? Very few were harsh on the players. Almost nobody, in fact-- it was all directed at the coach, and the implication was always there that these guys would be doing better with a better coach. And then it was Cuonzo himself that redirected it at his own players to motivate them. That was a dick move, and that's a big part of what makes me so angry with him.
