There have been NCAA investigations that have followed him throughout his career in different programs. Where there is smoke, there is usually fire. Being a fan of UK, you might be biased on this issue.
I am biased, I admit that. Hell, I'll even admit that I hated him and called him a cheater before he came to UK. All I have seen since he's been here for two years, however, is being the best recruiter of all time, fantastic charity work, recruiting the high character kids, being a great role model for them, working their asses off, preparing them for life in the NBA, and winning.
The two 'charges against him' are really silly. Rose was in Michigan taking an SAT (or was he??), hadn't even stepped foot on the Memphis campus, was cleared to play by the NCAA clearinghouse, was never proven to had done anything wrong, and Calipari somehow arranged for him to cheat on his SAT? Biased or not, I don't buy that.
Camby took money and after major investigations, Cal was FORMALLY cleared by the NCAA. Did he know about it? Who knows? NCAA says no, but ..
Now, in the past couple years Jim Calhoun has been slapped, Pearl fired .. Tressel .. I can tell you that Calipari is every reporters HOMERUN. He's under the microscope every minute of every day. Sorry, I said I was done. I REALLY don't want to talk UK here.
