I agree with this, but find it to be an unlikely outcome.
Wade and James are much better offensive players than Bosh. Bosh will be the no. 3 option to those two. I think that James will be the offensive initiator most of the time.
For a couple of reasons; Wade is older and beat to shit. I think he is ready to take a step back in responsibility. James is the bigger matchup problem for most opposing teams, and it will just be easier for the Heat if James has the ball in his hands, draws the double and then creates for Wade and Bosh, even if all they do is get the defense off balance, and Wade and Bosh get to make a play one-on-one. I think James is the better passer as well.
Of course, they will mix it up, but I think when on the floor together, James runs plays most often. With James and Wade they also will be able to have James or Wade on the floor for the full 48 minutes. The opposition is screwed in that regard. No letup.
No, I think James will be the dominant offensive force for the Heat. The real interesting situation to me will be who has the ball in the last two minutes. Who takes the last shot. Who is their "closer".
