You should probably be aware that the Suns were just as efficient with Shaq on the floor scoring points than they were without him on the floor. You might have thought it didn't seem to work, but D'Antoni did make it work. A top offense is only slightly less important than a top defense when championships are on the line. Basketball history tells us that. The Mavs won the title two years ago with a defense that wasn't top 10. Meanwhile D'Antoni's Suns teams were actually pretty average defensively, just not great. But if you swap out one of the worst post defenders in the league in Amare for the best post defender in the league in Howard, isn't that worth a few pegs on the defensive rating?
