The casual NBA fan may immediately associate the Spurs with "old," but contrary to common conception, the roster features an abundance of youngsters.
Second-year stud Kawhi Leonard leads the pack, having shown bright potential in his first year and a half in the league. Leonard has the makings to be a star, and has already established himself among the top perimeter defenders in the league.
Danny Green, the Spurs' Cinderella story of 2011-12, has also shown flashes of potential. The 25-year-old shooting guard is one of the league's best three-point shooters, and has also manifested a defensive aptitude in his short career.
Tiago Splitter, the team's starting center, is also on the rise, and though Duncan's shoes will be nearly impossible to fill, Splitter will prove to be a more than serviceable post option. He runs the pick-and-roll flawlessly and has added a collection of other post moves to his offensive game. He is also growing rapidly as a defender, and is among the league's best playmaking big men.
Other role players with high potential include Nando De Colo, Cory Joseph and Patty Mills—as well as international stars like Davis Bertans and Adam Hanga, whom the Spurs currently own the rights to.
Though none of the aforementioned—excluding Kawhi Leonard—has superstar potential, they are all dangerous role players, and in San Antonio's system, can help keep the future bright in San Antonio.
