That being said, for anyone that watched one second of basketball that Syracuse played last year, one of Southerland's main issues was that he COULDN'T rebound. He doesn't have a knack for it, nor did it look like he was particularly interested in mixing it up down low most of the time.
If we didn't play a zone, that's fine. He can play the 3 and the 4 and 5 men could rebound, with the guards helping out. All he'd have to do is box out. But since we do play a zone, he needs to mix it up with guys that are 6'9" 250. CJ does have a knack, does have a willingness to rebound and also has a much more fluid game than James does.
Between Joseph, Christmas, Fair and Southerland, there is going to be an odd-man out in the forward rotation. We all know JB will not go deeper than 8.5 (I expect Scoop, Triche, Waiters, MCW, Melo, and Baye to be locks for the rotation). Even if he goes 9, I have a tough time seeing Southerland in there, especially if Triche/Fair/Joseph can stretch the D consistently due to improved outside shooting.
Fair and Joseph offer so much more than Southerland in every other aspect of the game outside of perimeter shooting that it doesn't make sense for him to see many minutes over Fair or Joseph. X factor is Christmas. If he can't play or isn't ready (which could very well be the case), then you will probably see much more of James. But I'm not sold on him playing any more than 10-15 minutes a game. With Christmas being so highly touted, JB is going to give him every chance to get there -- likely at the expense of Southerland, IMO.
