Can UNC Survive

Can the UNC men's team survive losing it's top six scorers? They lost 4 to the draft and 2 to graduation. How will UNC recover from this loss. Their seventh leading scoring only averaged 3.7 points per game.
And what happened to these guys wanting to stay in school. Marvin Williams could have skipped college but he said he wanted to play college ball. He wanted to go to UNC. So much for wanting to play college ball. Yeah he played one year but he acted like he was going to stay longer.
Who will make the biggest impact? Felton, May, and Williams stock only went up these year while McCants dropped considerably. Honestly I believe Williams will be the best NBA player. There are many point guards in the NBA that can do what Felton does. May is a tweener. Not big enough for center not fast enough for power forward. McCants has the NBA attitude but he will just be average. Williams has the body like KG.
So where does this put Roy Williams and the UNC?
