Keep in mind, Golden State just signed Turiaf; assuming LA doesn't match, he pretty much makes Powe redundant.
Also, I'm not sure Golden State wants Scal. They said they have no interest in bringing Barnes back, so I don't see them salivating for a player who is a downgrade.
I know that they *do* like Azubuike, though. Out of Barnes, Pietrus, and Azubike, KA is the only one that stated a desire to bring back.
