On the Stack angle, I think most fans/media are unwittingly making a very large assumption. They have assumed that Stackhouse was solicited by the Mavs on the buyout-return angle. I don't think so.
There are logical reasons that the boomerang-to-Dallas idea originated elsewhere. And if the Mavs didn't solicit Stackhouse or arrange the deal in any way, then I believe the Mavs have covered their butts and have no exposure here no matter who blabs what. That's far better than having to worry about someone letting the cat out of the bag during the 30 days, or even on down the road, and the league then coming back and hammering them.
Why do I think this? Because it's been well known that the driving force behind this deal all along has been Kidd's agent, Schwartz. And it takes a deal-driver to come up with an out-of-the-box idea like this one where Stackhouse (with a not-so-tiny contract) boomerangs to Dallas. (Agents are movers and shakers in the NBA to an extent that outsiders rarely grasp.) So who most likely created the idea with NJ, of them getting-and-waiving Stackhouse to make the numbers workable on such a big money deal? Yep, Schwartz. Any rules problem with that? No. And one more reason why I see his fingerprints here, rather than the teams': because (not coincidentally) Schwartz is also STACKHOUSE'S agent. He's obviously juggling the contracts to help his clients play where they want to play.
It could have gone down 1000 different ways.
I'd guess that within his attempts to find a way to get Kidd out of NJ and to Kidd's preferred destination in Dallas, Schwartz created the idea, and first talked about it with Stackhouse. Then he suggested to NJ they talk about Stack in the deal, and discussed with NJ on a "hypothetical" basis the exact buyout amount it would take for Stackhouse to get bought out IF they trade for him. From there it could have unfolded down many various paths, but as long as there was no arrangement other than the agent telling his clients that he'd take care of them, it should withstand scrutiny no matter who says what when.
I find it compelling that while the yahoo writer and ESPN are stirring up reactions, Thorn and Cuban seem less than bothered by that issue. In the latest, Thorn specifically said he thinks they'll still get Kidd-to-Dallas done somehow - and that's AFTER all this foofara being written about the league source said this or that. I think they - as smart businessmen do - discussed the deal in such a way that even Stack's loose lips of what he WANTS to do can't cause them any real problem later.
These guys know the rules. They are careful businessmen who dot the i's and cross the t's with precision. And at the end of the day, it ends up being nothing more than a well-designed deal that was crafted carefully without creating any exposure.
