Roy feels his pain
Roy Williams was the guinea pig, the first coach of a major D-I program to lose his top seven players all at once thanks to the simultaneous loss of four underclassmen to the NBA. Now his coaching buddy, Jim Calhoun, is experiencing a similar exodus at Connecticut, though it doesn't appear Josh Boone is a definite goner at this point.
It would appear the NBA's new age-limit/year-of-college draft rule will only make ridiculous player turnover like this more common. Most of those players who before would've skipped college altogether to enter the draft are now leaving after one year. Those losses are felt more severely than losing a guy you never had in the first place, i.e. JR Smith in UNC's case.
