LeBron isn't MJ, he isn't that great of a scorer. He's a freak and a great finisher. But he isn't very good at creating a shot (or making a shot) which is the most important aspect of being a scorer. I think he's closer to Magic since he's is an amazing playmaker. I think that LeBron runs point in Miami. Wade is a great scorer, LeBron is a great playmaker. Put them both together and you can't defend them. Not to mention Bosh.

Wade
Miller
Bosh
Really big white guy
Recipe for success.
