As far as CJ is concerned, when the team is loaded with talented offensive players, he sometimes needs to balance being more aggressive versus letting the guys hitting shots continue to hit them. I forget which game it was, but he hit several clutch shots to keep Iowa in the game.There are zero players to be worried about. They are all having anywhere from record breaking to fine seasons.
If you were going to pick someone to "worry" about, it would be Toussaint. He just isn't a point guard and I don't think he ever will be, but he's a better Anthony Clemmons and is a nice role player on a good team. Even a player like Nunge who has been pressing way too hard on the offensive end still goes out and gets 10 rebounds.
