KG is untradable, plain and simple. Pierce might have some value to a contender with a hole at small forward, but we need to make sure we get something good back - not just expiring deals.
Cleveland and Orlando are set at SF, Atlanta does not have appropriate contracts / picks / young players to trade, so the East is out.
Lakers are good with Artest, and San Antonio does not have the assets. Portland does not really have the assets either - we are not getting Oden or Roy. Fernandez, Outlaw and Blake are not enough. Their pick is low.
Utah could be interesting.
They have expiring deals (Boozer, Korver), replacement talent (Kirilenko), young talent (Brewer, Miles, Koufos) and solid picks (NY #1).
Are Pierce and Walker for Kirilenko, Koufos, NY #1 and Utah #1 equal value?
