I think D.Rose will win it, and he completely deserves it IMO.
To me, Most Valuable Player means who helps their team the most. LBJ helps the Heat enormously, but they wouldn't be completely lost without him.
Without Rose, Bulls are a lottery team. The Bulls are 2.5 games out of the #1 seed in the East despite them playing most of the season minus Boozer/Noah (I think they've only appeared in like 9 games together this season or something. Not 100% sure, anyone have the exact #?) But they are in position to threaten for the top spot in the East despite some MAJOR absences, and that's because Rose is carrying them night in and night out.
