The fifth spot on this list was the toughest to make a decision on. Leslie McDonald could be considered indispensable with P.J. Hairston missing games and no other shooting guard on the roster. On the other hand, there is the center position, which is stacked with three players. None of them, however, have proven anything at this level.
It's a bit of a toss up here, but with the three-point shooting of Marcus Paige and a backup point guard in freshman Nate Britt, the center position may be a bigger factor. The Tar Heels were vulnerable last season without an impact center to dish the rock to, and power forward James Michael McAdoo was forced into double- and triple-teams on the regular.
He was even moved to center to make room for another scorer in Hairston.
This season has to be different, and the most likely center to step up to the challenge is sophomore Joel James.
There is no questioning James' physique. He's a rock-solid 280 pounds and stands at 6'10". The same can be said of his surprisingly soft shooting touch.
The questions surrounding James are about his mental errors last season. He was a fish out of water as a freshman. He often dropped passes, picked up petty fouls and traveled during simple ball rotations.
When his head wasn't getting in the way, though, James appeared to be every bit the monster Roy Williams was hoping for when he recruited him.
He was an efficient scorer, dropping 51.7 percent of his shots last season. He was also snatching up a rebound every 3.9 minutes, which should increase this season with a summer of coaching.
Good luck to the opponents trying to box out that frame.
If James improves on the defensive end and becomes more confident with his offensive game, he will prove to be one of the most indispensable players on the squad.
