I think the Vaughn signing was a smart one, because he's capable of providing good defense and can run a ballclub, too. You don't play the point for Jerry Sloan if you aren't a decent decision-maker. Both as a defender and as an operator of the offense, I think Vaughn is a major step up from an end-of-the-road Van Exel, though he'll never be the offensive weapon that Nicky could be. I think Vaughn affords the Spurs some luxuries against teams that want to go smallish. I still think that if he needed to, Pop could play Vaughn and Parker together to try to offset some of the speed that the Mavericks try to throw at the Spurs with Harris and Terry. Parker can slide over to a functional 2 guard while Vaughn runs the show, at least for stretches of time.
