Not sure how trading a star for a bunch of overpaid role players burnishes his credentials. Makes him look like a Laker stooge, IMHO - Chris Wallace redux.
They'd still be competitive for a playoff spot.
A rebuilding trade would lead to a lottery spot for sure.
The NBA doesn't care about any of that. They're trying to sell the club with some degree of promise - hence the request for younger players and picks, not pawn off a team over the cap and loaded with overpaid players on the downside of their careers.
It was a horrific trade, and the league - which owns the club - has every right in the world to veto it. The litigation threat is laughable.
