just to clarify, stats aside, there' s no question that
Bosh is on fire this year
he's having his best offensive season by far, and even if he's still had a few bad games and is still partially unable to overcome tough defenders (no longer rasheed and garnett, but the likes of josh smith, varejao etc).
I don't think he's as good as duncan and nowitzki though (among PFs), but he's jumped in front of gasol and stoudemire this season. And probably next season he'll become the best offensive PF in the game.
Of course, unfortunately some of the improvement is due to him focusing exclusively on offense some nights, and you don't really need any stats to see that. There's nights when he's worse than
Bargnani was last season, and that's too bad because that's all that separates him from having an MVP caliber season.
As for his role within the team, nights like on wednesday notwithstanding, we're much better off when
Bosh puts more effort into defense for the simple reason that we have a ton of offense without him, it's D that we're lacking. If
Bosh would play as hard on D as he does on offense, we'd be a much much better team.
