A slight surprise about Richards; I thought he was going to be able to pressure the Spurs to bring him to Austin, but I guess the shoulder surgery really put a damper on that plan. I wouldn't be surprised if we see him as early as the 2011-12 season, though if there's a threat of a long lockout, the Spurs may want to keep him overseas one more year and not risk having him lose a year of development due to labor strife.
As for the role of 6th big, the Spurs probably have two major options:
1. A cheap veteran big man who they can shove on the inactive list for long periods of time, but should be able to contribute if called upon (i.e.- what we thought Ratliff was going to do last year).
2. A D-League eligible young big man, who the Spurs can look at for the long haul, and may be able to play in emergency situations.
The more I think about #2, the more I like the idea of James Gist in that role. Out of their options for D-League eligible players, he's more ready to contribute than most, and his length and body-type isn't duplicated by anybody else on the roster. In an end-of-the-bench sort of way, he would actually fill a niche in the roster, a 3/4 hustle-man who can get out in run with some of the other youngsters.
I've said before that this summer is likely make-or-break for Gist as a Spur; he's done his loyalty thing by heading overseas for a couple years, and now they should make some sort of decision one way or another. I said a few days ago that the Spurs have two major options:
If the Spurs bring him into training camp, they'll likely be choosing between these two options. If he impresses enough that they execute option a, look for him to spend 80% of his time in Austin, shooting perimeter jump shots and guarding small forwards.
