I'm just not sold on Bosh being a good #3 option. If he planted more in the post, the Heat would be way more dangerous, IMO. Think about it: As a post player, he's pretty darn good. The Heat would be able to go to him down low more consistently, which will force teams to eventually double-team him. It will allow for more cuts by James and Wade, and the perimeter shooters will have a field day if he passes out of the double team.
I'm tired of seeing Bosh catch the ball 18 feet out and relegate himself to being a jump-shooter. That's a decent part of his game, but he's not good enough outside to make it his focus. His target area should be the high post, at worst.
