biggest difference between asik and perk is that i've seen several playoff games where, late in the game, asik was the best player on the court. never seen that before from perk. asik has an incredible motor and a good feel for the game.
asik can be a legit game-changer. with that being said, asik needs to be on a team with scorers, so he can focus on what he's best at. i wouldn't give up any assets to bring him to the rebuilding c's. but if i were OKC, golden state, the knicks, pacers, even the spurs... i would do whatever it takes.
it should also be mentioned that asik has been a massive malcontent this year. he was playing on a decent team with title hopes, and he's done more damage than good due to his own ego. that's not celtics basketball. i want nothing to do with him.
