Calipari doesn't have to cheat at Kentucky. It's a legendary program and a place truly obsessed with basketball. Players know they can show up for a year or two, challenge for a national title, live like kings and go make millions when they're done. Calipari's convinced recruits that they can market themselves better by playing together than by going to a lesser school and being a star there. And he's right. Not many coaches/schools could pull it off, but Cal/UK can. I don't doubt he was a massive cheater at Memphis and UMass, though.
I don't see the system as anything to complain about.
