UNC's success next year is largely dependent on if Berry comes back. And as
@dukiejay noted, it doesn't seem likely he will leave. Berry, Pinson, _______ , Maye, and Bradley could compete and possibly win the ACC. If the underscore is filled with Kenny Williams, it's less likely. If it is Knox, the chances rise dramatically.
IMO, losing Berry would hurt worse than Jackson. Roy's system is hugely dependent on great PG play, which can be seen in the differentials when he goes out of the game. He also played most of the year on a bad ankle. He was tearing it up before the Tennessee game and just wasn't the same player when he came back.
