I don't know a coach in America that abides by the 20-hour per week practice rule. Ditto summer coaching. Same with contacting, lying to, and assisting recruits. Those are all rules that all coaches break.
Many HS recruits-- I'd guess half of them-- have academic or integrity questions in their background. About a quarter of them have serious questions. Every coach looks the other way if a recruit is good enough or if they need him enough. All of them.
Bill Walton smoked pot while at UCLA. Wooden knew and ignored it.
William Avery (among others) would have never been admitted to Duke unless they could also play basketball at a superior level. Roy Williams took a kid who was basically passed through high school after he flunked out at Kansas. John Thompson took a kid who started a race riot on his team and the entire campus cheered. Adolph Rupp paid kids for jobs they never did.
You say it's only Calipari who's cheating? Please.
IF Cal is cheating (and I maintain that he's never been caught doing anything remotely bad) the way fans claim, every prospect in America would go to his team. (Or, at the very least, he'd get his pick of prospects across the nation.)
Are they all going to Kentucky?
Nope.
They go to Kentucky. And Duke. And North Carolina. And UConn. And Kansas. And UCLA. And Butler. And everywhere else.
If one cheats, they all do.
