I think the Jazz would have to offer a fairly generous sign-and-trade package to not look like jerks, but it could be done. You have to understand though, the Nets have no leverage here. Someone is going to have to do them a favor just to offer a sign-and-trade. DWill could sign with the Magic, the Mavs or the Lakers in basically 60 days, and the Nets will get nothing and be decimated.
So if the Jazz offer a package to the Nets, we look like good guys actually.
If I were the Knicks I'd offer Amar'e + Lin + draft picks for DWill (if the Nets are desperate enough).
Win win for both Knicks and Nets.
That'll definitely beat our offer...
