This is going to be Miami's problem, and the reason why that great Bulls team would shred them. Let's say Dwayne Wade decides he is content to be a complementary player to LeBron, setting him up for easy buckets and taking open jumpers when LeBron penetrates and dishes. That's great... except that there are about 50 other players in the league that can do that pretty well. At that point he won't be Dwayne Wade, he'll be Mo Williams. Which is fine, but then the Heat seem a lot like LeBron's Cavaliers teams, don't they?
The paradox for Miami is that there is only one basketball and they have three marquee scorers. I think Bosh will adjust well to a complementary Scottie Pippen-type role. But that still leaves you with Wade and LeBron playing the same role on the team. I know Wade is injured right now, but when the Heat had all three guys on the court yesterday it was one of their worst lineups. Contrast with the Celtics' Big Three, where all three guys have a different skill that complements each other. The Bulls' best players fit together in a similarly tight way and that's why they won 6 titles.
It's going to have to be Lebron that makes the role switch. He's going to have to become Oscar Robinson/Magic Johnson type player. He has the ability to do so. Then LeBron becomes a better version of Pippen and Wade fills the Jordan role of scorer (obviously not as good) Bosh is the low post scorer and you fill the other two positions with either two knock down shooters or one shooter and one defensive low post player.
All of that depends on Lebron though. Wade doesn't have the same skill set to be able to make that switch.
