DaQuan Jeffries, SG
On May 15th, the Spurs filled out their maximum allowed players by claiming shooting guard DaQuan Jeffries off waivers after the Houston Rockets released him. As Spurs beat writer Tom Orsborn succinctly put, I wouldn't expect him to be part of the Spurs next season, unless we're talking about the Austin version.
Verdict: Let go (or play in Austin)
Quinndary Weatherspoon, SG
While he had the best couple of games of his young Spurs career to close out the regular season, it's hard to see Quinndary Weatherspoon being a big part of this team's future. In two seasons, he's shown up in just 31 games and is getting fewer than seven minutes when he does see the court.
Weatherspoon has shown flashes of potential, but there are just too many guards ahead of him on the rotation, so he'll likely continue developing in Austin unless he finds a home elsewhere as a free agent.
Verdict: Let go
Keita Bates-Diop, SF
Another free agent seeing limited minutes, Keita Bates-Diop has shown some promise in his garbage time minutes. The 6-8 forward has shown he can drive to the basket and stroke the three on offense and is a capable defender.
The Spurs will need to keep adding 3-and-D guys similar to Derrick White and Devin Vassell next season, and Bates-Diop has the potential to be the next in line. Although he played about half as much as he did in Minnesota and Denver, the Spurs could do worse than giving Keita some more time to show them what he's got.
