Big men always look like better scorers than they are, because they get all those gimme points on putbacks, open dunks, etc. The kind of points any big man gets just by standing around the basket. (Howard being an example — he can overpower guys, but Lewis is definitely the more dangerous scorer, despite their PPG stats being similar.) If Bosh played for the Magic, he wouldn’t get a lot of those points — Howard would. And the ones Bosh got would just decrease the number Howard got. They’d be working at cross purposes on offense.

Moreover, Lewis definitely has the more varied offensive game. And he can shoot the three — he’s the best three-point shooter in the NBA — which is crucial. Bosh has a few post moves — I’d like to see him try post moves with Howard (and Howard’s defender) already in the lane — and a mediocre mid-range jumper. He also has the seeming inability to recognize that he shouldn’t be shooting the three.

Bosh is basically Jermaine O’Neal — a good PF who’s not a dominant scorer or a dominant player. He’s very good at exploiting the opportunities for scoring and rebounding that come to a good big man. But he doesn’t have any really amazing strengths. He is reliably very good, and that’s also his peak.
