Barnes's single biggest problem is that he's on a team with a bunch of chuckers. It's hard for him to get shots. For a guy that needs to get in rhythm, taking one shot ever 10 minutes just doesn't cut it. If they get rid of one of the guys who don't even look at anyone else once they catch the ball, Harrison will have a great chance at breaking out. In fact, the rest of this playoff series could be a key indicator now that Lee is out. I'll be watching closely.
But my pick is John Henson. He's averaging 22 points, 17 rebounds, 2.6 blocks per 48 minutes on the season in limited action. But his numbers are even better when he gets good run: last 5 games of the regular season he averaged 34 minutes per game, 15 points, 15 rebounds, 2.8 blocks per game. And judging from the Bucks' first playoff game, he's made it into the playoff rotation (20 minutes vs. Miami Game 1).
Kendall Marshall could be a good choice, again depending on his run. In his 3 starts near the end of the year, he averaged 12.3 assists to 2.3 turnovers per game. As a rookie! But it'll probably be another year or two before he really gets big minutes. His passing is as good as anyone in the game, but he really has to prove he can shoot at the top level.
Collecting all Tar Heels (UNC uniform preferred).
