I'm not sure which one you're attributing to each sentiment, but if you think Pitino "loved the big blue nation," that's got to be a joke because you've completely reversed it. No coach at UK - or probably anywhere in college historically - had less respect and more almost disgust for a people than Pitino did for Kentuckians. I was at UK during this time and believe me the common fan was the great unwashed masses in his mind - especially from outside Louisville or Lexington (although he didn't want anything to do with those folks either). Some wanted to attribute the attitude to his wife, but I think he was more "I'm so much better than these people" than she was - she just preferred NY over Lexington.
Calipari on the other hand, came from self-perceived humbler beginnings. He was a coal miner's grandson and he was raised blue collar working-class. I think Calipari could make all the money in the world and isolate himself from fans for years and still could never approach the level of disrespect Pitino had for the fanbase and people of KY. You can think whatever you want, of course. But I would remind that just because a guy is a great basketball coach and we enjoyed how the teams played, doesn't make him a good person. Pitino wasn't a good person when he was at UK in my opinion for the reason I've stated (not because he left or coached at UL), and suggesting he was some great person while at UK and then mysteriously became "bad" when he started coaching at UL is delusional transference.
But again, if we want to talk about being a great coach of college basketball, then I'm with you 100%.
