Should be this guy, but he wont get it. Lakeshow wouldnt be above .500 without him and they wouldnt make the playoffs. I think Kobe>Dirk>Nash for the mvp. Both Suns and Mavs most likely make the playoffs if Dirk and Nash werent there. If Bynum pans out, which I think he will, watch out!
EDIT: Suns could easily still win their division with Barbosa as a starter.
