Leuer will be AWFUL in the NBA. He has no lateral quickness to play defense. Yes, he's tall and can shoot, but his advantage comes from his height and in the NBA that will be negated. He's too slow to defend 3's, too skinny to defend 4's.
JuJuan Johnson is a legit NBA player and should go much higher than 28. He's like Hakim Warrick with a jump shot. He'll never be an All-Star but he's worthy of being in the league.
Battle is really nice, but he's pretty small and his PG skills aren't that great. He'll have a hard time making it.
Lighty has no chance. He can't dribble well enough for a 2, not enough athleticism.
Buford can be a solid back-up 2 someday.
McCamey will do nothing.
Sullinger can play, but he's not very vertical with his game. He's DeJuan Blair, maybe a little better.
