Powe made a big mistake signing with the Cavs. He should've gone to a crappy team and try to get playing time for 1 or 2 years.
Well, there is a chance the Cavs look significantly different next season, and since that is when he will actually be getting his explosiveness back, that is really all that matters.
I don't think there's much chance of it at the moment as far as PF goes. Jamison is still signed, Hickson is signed, Wild Crap is signed, Williams a restricted FA.
It'll be quite hard to move these guys around in a way that gives Powe a good shot a extensive playing time.
There's a lot of in hindsight going on here, since they certainly looked thin in the PF position during FA, but yeah I think it will end up being a mistake.
