Also that would kind of taint the championships IMO. It wouldn't be a "normal" NBA team. What if a bunch of superstars decided to do that? It would just ruin the league and turn it into the WWF
There's no guarantee that it works, regardless. Guys get hurt. You need a bench. You'd really prefer to have Wade play the SG. Guys all have to commit to playing D. Gotta share the ball consistently.
Celtics tried the three-superstar thing, and it worked. Lakers tried it with Kobe/Shaq/Mailman/Glove, and failed.
I could see Wade and LeBron teaming up together, Wade seems like the one superstar in the League who's most comfortable sharing the spotlight. Bosh, I'm not sure he's quite in the same league as those two.
