Well because he invited Drissa back, who really wasn’t a contributor at any point thus far, my only guess is that much of it is/was social/disciplinary, academic or other reasons and not basketball talent. Pitino said he’s not done talking to them yet and may invite more back so we shall see a bunch more shake out by early next week I assume.
I don't buy the argument that all these guys were bad apples.
And it doesn't really jive that he's keeping the guy who recruited all these undisciplined troublemakers that he doesn't want.
As for Joel and Drissa, he's keeping the best and worst players. That the easiest thing to do immediately.
Rick just wants better, more talented players. This broadbrush stroke that all of them are a mess is not good.
