Assuming all three stars play, it'll be interesting to see how they work together. To me, the most overlooked reason as to why our Big Three have worked together is how well their games compliment each other. Due to their differing skillsets and all three's ability to hit the open jumper, they've managed to be effective without negating or repeating aspects of each player's game.
I'm not so sure the Heat have that.
Yes, having three superstars on the court will make it harder for teams to guard them and will conserve each other's energy; however, if all they're going to do is run isos for each of the three superstars, they're largely negating the benefit of having three superstars out there.
And that's not even getting into the whole aspect of whether the three can share the spotlight and the ball.
Certainly Miami could be quite scary and quite good. But they could also be a younger version of the late-'90s Rockets, a team that not only was too old, but also had three superstars (first Hakeem, Barkley, and Drexler, then Pippen replacing Drexler) whose games didn't compliment each other. Having Hakeem in the post, just meant Barkley wasn't being effective there and meant Pippen turned into a jumpshoter, something he wasn't. The same could happen in Miami where LeBron (or Wade's) ball domination could turn Wade and Bosh into jumpshooters, which certainly isn't either's forte.
I agree. When the (real) Big Three were brought together in 2007, I instantly knew what we had not only because of how great all three were, but because of how complimentary their games were.
Presumably, Wade and LeBron will handle the ball the majority of the game. LeBron can move without the ball, but Wade isn't as good. These guys are almost useless on offense without the ball, all of them. You can't have two guys penetrating with one ball while another is hanging out in the post. If two of them are going to be 15+' jumpshooters, the whole league will be fine with that.
On defense, Wade and LeBron are rather good one-on-one. But how well they compliment each other remains to be seen. If they indeed plan on playing Wade and LeBron alongside Miller when he returns, that assuredly creates matchup problems. Matchup problems for the other team, but also for themselves. Which coach can exploit those weaknesses most will get the W's.
And then there is the whole Center issue they will have to deal with.
