There's a number of young players going into training camp that the Spurs may want to keep in the mix, but only one open roster spot left and only so much playing time to go around. That may leave them leaning on their D League affiliate even more than usual next season.
The Austin Spurs (née Toros) have played an important role in bringing along the varsity team's younger players for years. Guys like Cory Joseph, Kyle Anderson and Jonathon Simmons have had their development facilitated by regularly making the trip up I-35 to get as much playing time as possible and work on specific areas of their game.
