I gotta disagree along with several others. These 2 situations were nothing alike. Pitino left UK in as good a shape as anyone could have. So much so that his successor won a natty in year 1. He left for the opportunity to coach the Celtics. A dream job for him and likely the only one he would have left UK for.
Meanwhile, Cal decided at some point that getting guys drafted was more important than winning. When he left he took all his recruits and players with him, leaving the cubbard 100% bare.
Pitino really got into trouble with UK fans when he took the UL job. That made public enemy #1 at that point. UK fans were bummed when Pitino left for Boston, but they hated him for going to UL. But as far as the circumstances of their exits, nothing alike.
