When I do my formal rebuttal, I'll try to get into it a bit more, but I absolutely welcome Hedo at the PF position. First of all, since at least 2007, every time he's played there (which has always been in very limited minutes), he's been abused physically, with the men he's been guarding putting up big, big numbers.
Second, if Hedo is in the game, Sacramento has a huge rebounding advantage, even with Howard in the game.
Last, Hedo trying to guard either Boozer or Randolph is going to lead to additional fouls on the inside. Some of these will obviously go to Hedo, but others will be on Howard. With Howard in foul-trouble, Phoenix crumbles.
