That's all fine and good, but you shouldn't be able to remove the MVP from the team and they still win. The Heat would still be bad ass with Wade, Bosh and Ray Allen (not to mention Udonis Haslem, Lewis, Birdman, Battier, etc..)
To me, the MVP is the one who makes the difference on his team. That's why people were saying he would be giving up the MVP if he went to Miami, not just because of touches, but because two super powers on the same team cannot produce a league MVP based on how it's almost always been decided.
