?? Er...why not? They are trying to repeat, and their window is right now. They also have the rare coaching legend who is going to think he can deal with Ron.
As a young unformed team going nowhere Atlanta isn't going to want any part of Artest. Chicago...guess its possible, but with Dneg and Nocioni already there, not sure where/how he fits. He plays their strongest position with their brightest young star. Who is sane.
The only thing I could possibly see is that Chicago is obsessed with defense and they may need to resolve their SF logjam before free agency hits -- I'd assume either Deng or Nocioni would be in the deal and the other would come off the bench. The one thing they lack is perimeter defense. Deng is ok, Nocioni is actually a good post defender, but unless you count Thabo Sefolosha they don't really have a great perimeter defender.
But Artest and Skiles? Can't imagine that would work. And they already have one headcase in Ben Wallace. And they're waiting for Kevin Garnett.
I think the list of reasons they wouldn't is a lot longer than the reasons they would.
PS: Oh, and I think Artest in Miami is almost too good of a fit to even consider trading him there. You have all the ingredients for a good mix -- an alpha scorer who even Artest knows he's not as good as, a veteran in Shaq who Artest would respect, and an alpha coach who Artest would respect. That's probably the most ideal situation for him, and I'd have to think Miami is confident that they could incorporate him.
The problem from the Kings standpoint is that an expiring is not appealing at all. It's one thing for someone like Bibby, who is overpaid, but there's no hope whatsoever that the Kings could sign equal talent with $7 million in cap space. So you need to get close to equal talent back in a trade and hopefully a pick. Otherwise you're left with basidcally nothing.
