Iverson can move well for a big man, he is athletic. He is not just some tall oaf like most make him out to be. "Having good feet" means that his footwork in the post is, well, good. He only has a few moves with his back to the basket, a decent drop step, a little up and under and a hook shot. His problem is that he rushes when he makes a nice move in the post, he bricks the shot too often. He just needs to play with more control and confidence. He is only a sophomore, so he is inconsistent. Look at the games he played in California. Double-doubles in the first half.
Devoe is a scorer. He will put up a lot of shots, but 90% of them are great looks. He can handle the ball fairly well and can score in transition. The shots will start falling from the outside...when that happens, look out.
I think you need to remember these guys are still developing and players go through ups and downs in their careers. Look at Blake. The guy was absolutely torn to shreds on GH last year, now he has found his confidence and is really stroking it. Sophomore slump, or whatever you want to call it, might be a factor...but I think this is just a natural up and down for Iverson/Joseph. I'm not worried at all, both are very key this year and especially into the future.
They are my #1 and #2 guys I like to see come off the bench.
