While I agree that coaches help their players get recognized and want them to do well, you're making too light of it, imo.
Here's what I mean ... Calipari urged people to not overly worry about the 'attitude' problems of Cousins, that it's more immaturity than bad attitude. I would assume most here would agree Cousins is a very ggod player and will get better. Cal pimped Tyreke, Wall, and a couple others, but when asked about Daniel Orton he (not publicly) warned some franchises about his huge bust potential. He told some teams of Patterson's short-comings, he told a few teams that Knight will be good but not a sure-fire starter. He urged TJones to come back and work on his game and gain some maturity. He has been pretty real about his players, whether you agree or not.
I know, for a fact, that Calipari believes Enes will be a top-notch player in the NBA (agrees it will take a couple years). He could be wrong, but he's being sincere. I know, for a fact, that NBA personnel trust his opinions and it does him no good to lie to them about how he believes a player will transition.
