Who's to say you couldn't have both?
Just for entertainment's sake, what if the Spurs could pawn off RJ and Splitter for Maggette and Randolph (throw parts in from either side if you wish) and still had the expirings and a first-rounder, if needed, to acquire Thomas and Salmons?
I'm just spitballin', but Splitter to GS could give them a cheaper replacement for Biedrins, whom they could include in a separate deal to upgrade their roster, and they'd rid themselves of Maggette's contract; RJ's at least a name and someone that the fan base wouldn't be up in arms about acquiring. (he'd look much better in that offense)
The Spurs get one of the most improved players in the league this year and a guy who's suited to be a nice 6th Man moving forward; he's an upgrade to RJ this year (going out on a limb there,
Blackjack) and I wouldn't vomit as profusely with him at the 4. But the key to this would be the acquisition of Randolph, someone who could be a franchise-level player down the road, and someone the Spurs wouldn't likely have the opportunity of acquiring under normal cir stances; losing Splitter would be a small price to pay, imo, if it's to acquire someone of Randloph's ilk.
If the Spurs still had the assets for the Thomas-Salmons deal, it'd be virtually the same rationale on the basketball court for this year and for the evaluation purposes of next year. You'd have Hill, Blair, Randolph, Thomas (should they see him worthy) and Hairston as your developing youth and good assets to mix and match, which would negate the loss of a first-round pick (should it be required in this trade).
It's not real well-thought, just kinda typing stream of conscience, but it's seemingly feasible and, at the very least, shoot-the- worthy...
