He already is back to being an NBA player. The Grizzlies signed him up for this year and next.
Just saying that the Spurs need to take some risks on players with a lot more length. Right now the Spurs aren't taking any risks and just signing guys who 'come early and stay late'.
The way the Spurs defend without getting called for fouls is that they rarely jump. To do this and be effective you need a lot of wingspan. Aldridge,Gay and Murray have this. Anderson, Kawhi, Green had this. Duncan had this. Now we got short armed folks like Forbes, Bertans, Belinelli, Mills that aren't effective in defense.
