I believe that Spurs have made most of the moves that they're going to make. If we assume that the imminent signings of Manu Ginobili and Pau Gasol then most of the signings are pretty much complete, at least as far as I can see in terms of the main players on the roster. Granted, there might be a few more signings or people that surprise during training camp. Here's where I see the roster as the season begins:
PG - Patty Mills, Dejounte Murray, Derrick White, Tony Parker
SG - Danny Green, Manu Ginobili, Brandon Paul
SF - Kawhi Leonard, Rudy Gay, Kyle Anderson
PF - LaMarcus Aldridge, Davis Bertans
C - Pau Gasol, Joffrey Lauvergne
Officially, Bryn Forbes (who has been lighting up the Summer League) and 2nd round pick Jaron Blossomgame have not yet signed contracts with the team, but to be honest, I've never been 100% convinced about Bryn Forbes. He has the ability to be a Roger Mason or Gary Neal type player at best and frankly Patty Mills works out better. I also am not sure what exactly will happen with Adam Hanga joining at least training camp, hopefully he'll pan out slightly better than Livio Jean-Charles.
