If the Spurs wind up draft-n-stashing the first rounder and pulling an only passable player like Rayshawn Terry with the Milwaukee pick, that would IMO be a disaster. In my estimation, this team needs to add two good young talents who are not currently on the roster. Though he isn't exactly 'young', one of those two can be Luis Scola.
There will be a roster crunch, sure. The way I see it:
Robert Horry is retiring, his spot is open.
Beno Udrih - this is the last time he will have any real value, is a cheap contract, and might still flourish in another system; he will be traded.
Jackie Butler - do they want him anymore? I could see him go in a package or to wherever Larry Brown is, etc. He's cheap but doesn't seem to be what the Spurs need. If they can draft a Craig Bradshaw, Butler is absolutely gone.
Melvin Ely - depends on what happens to Butler and other big guys. His spot is essentially open.
Fabricio Oberto - slim chance he opts out and goes overseas, but I don't think so.
James White - that decent performance gave a little pause, although against GSW. Keep, unless a better young SF prospect can be had, which is definitely possible.
Jacque Vaughn - resigned.
Francisco Elson - kept.
So... two spots will open up, at least: Horry's, and either Ely's or Butler's (or both). This could very well be the summer Brent Barry is traded, too, if the Spurs think they can get their young SF packaging him with Scola + picks or something like that, although of course that wouldn't necessarily open a slot.
If I were the Spurs, I would prioritize moving up in the draft. After that, they should have contingencies in place depending on what players become available. I doubt Ian Mahinmi comes over this summer. And again, I think the Spurs need two valuable new players to come in this summer
