While I think Miami will improve, there are still 3 glaring questions.
First, will they all actually defer to each other? I think the answer is yes, but if they get off to a bad start, will finger point ensue and this whole thing fall apart?
Second, can their games actually compliment each other? I'm less sure about this one. Unlike Paul, Ray, and KG who all function well without the ball in their hands, historically all three have needed to dominate the ball to be effective.
Third, assuming they two parts one and two, the question is whether they can be effective in these roles. Even if Wade and Bosh embrace shooting the 18-foot jumper, can they do it when they don't touch the ball for the first 18 seconds of the play? And before you smirk at that notion, keep in mind that Ray Allen struggled with this his first year here. Many of us were perplexed as to why Ray was missing wide open jumpers. And the reason likely was that he wasn't used to not being involved in plays and essentially functioning as a role player 75% of the time.
I'm not sure Miami's Big Three can overcome that.
They may. It's way too early to know. But I think that could be their downfall.
