1) The best stats =/= a deserving MVP candidate. Maybe MBP, but that doesn't quite exist.
2) If both teams are comfortably in the playoffs, why should wins be the deciding factor? There is nothing in the MVP criteria that says anything about wins. The wins thing is only a precedent the voters set up for themselves a while back, and now have to live up to every year to avoid murking up past MVP selections.
We've established that these guys are both future HOFers. Cleveland, without LeBron, is still in the playoffs, though towards the back end. Miami, without Wade, is sitting in the basement with the Wizards. IMO, that's what it comes to.
