Patty Mills and Aron Baynes don't play much, but both players are useful end-of-the-bench guys.
15. Livio Jean-Charles, Small Forward
The 28th pick of the 2013 draft was not expected to play for the Spurs this season anyway, so consider this an update on the 6'9" combo-forward.
Livio Jean-Charles hurt his right knee during the FIBA U-20 games, and the injury required surgery (h/t Project Spurs).
Despite this minor setback, Jean-Charles is still an exciting prospect, especially since he will not turn 20 until November.
14. Aron Baynes, Center
Aron Baynes had a fantastic summer league session, averaging 12.0 points, 10.5 rebounds and 1.3 blocks while playing 26.3 minutes per game.
The 6'10" Australian is still the third option off the bench, but Baynes has shown he is a capable rebounder when he is on the court .
Hopefully Baynes gets a few more minutes this season as Matt Bonner nears the end of his career with San Antonio.
13. Patty Mills, Point Guard
This offseason, Patty Mills picked up his $1.1 million option to remain a member of the Spurs. Mills did this despite the fact he likely could have signed with a team where he would receive more playing time.
Mills has played 16.3 and 11.3 minutes per game over the last two seasons, respectively, with his light workload all but disappearing during the playoffs.
With that being said, Mills is still a valuable insurance policy should Tony Parker suffer an injury.
12. Jeff Pendergraph, Power Forward
Jeff Pendergraph signed a cheap two-year, $3.6 million deal (h/t Hoopsworld) with the Spurs, and he provides extra depth at power forward.
Spurs.com's Ken Rodriguez says Pendergraph brings a "sweet package of energy and IQ." Rodriguez sure makes it sound like Pendergraph and Patty Mills will combine to form one awesome cheerleading squad on San Antonio's bench.
Pendergraph will essentially take over the role of now-departed DeJuan Blair, playing some garbage-time minutes in place of Tim Duncan and Boris Diaw.
11. Matt Bonner, Center
Matt Bonner is entering the 10th season of his NBA career, but the 6'10" veteran can still stroke it.
Bonner shot 44.2 percent from behind the arc last year, and that is what keeps him on the Spurs roster.
He's not necessarily a defensive liability, but Bonner isn't exactly a great defender, either. With that being said, his outside shooting will certainly be a weapon once again during the 2013-14 campaign.
