I don't see the change you're talking about.
If you go back into the past, you see kids who were ripped in the past by other fans nationally, and here I'm talking about Khalid El-amin, AJ Price, Marcus Williams, etc., even Thabeet. Or Jeff Adrien. All were quality kids. I don't know much about Adrien's family, but we know that the first 3 came from tight families. I remember an article from a Pittsburgh paper in 1999 that said that, although UConn won the game, the game was not won by student athletes. And why? Because UConn's upperclassmen were black compared to Duke's? Is that why? That Duke team had several players go pro or leave Duke and never get a degree: Chris Burgess, Corey Maggette, Will Avery, Elton Brand, etc. Whereas UConn had seniors like Ricky Moore, Rashamel Jones, and a bunch of other solid kids. For all we know, they got their degrees. No one other than Rip Hamilton (a junior) left early that year. So why the perception?
This is a racial thing for many reporters and onlookers.
I just don't see the difference between Daniel Hamilton, Sam Cassell Jr., Rodney Purvis, and the players from the past.
