Jeff Green is a tweener-forward, like Antawn Jamison. He doesn't really fit at either forward spot. For some teams (like the Knicks now or the vintage Suns), that might work. For us it's completely unnecessary.
As for the center spot, Shaq can't play big minutes, and whose to say he won't go down with something big? he hasn't been a picture of health these past few years. JO'N can be counted on for absolutely nothing, even when he's not 'injured' his body is just too fatigued to give us much. Krstic is actually going to have to play, and he's useless. Have fun hiding his sorry ass, Doc and Frank.
