4. Tre Jones (Age: 21)
There's a lot to love about Tre Jones. He plays hard-nosed defense, is a great character guy, is quick to learn, and plays within himself. In the Summer League, he also showed his often-criticized offensive game has taken a significant step forward.
After getting expectedly limited play in San Antonio in his rookie year, the table is set up for Jones to become the backup point guard behind Dejounte Murray. Not only did he show an improved drive and playmaking in the Summer League, but his jump shoot looked smoother than ever in Las Vegas.
Already having the defensive side of the court down, the growth of Tre's game on offense will really tell the Spurs what they have. If he becomes a multi-dimensional guard playing behind another multi-dimensional guard in Murray, the backcourt rotation for San Antonio can truly be special.
Gregg Popovich can go a number of ways with his point guard rotations this season. Although the position isn't his specialty, Bryn Forbes is capable of playing it and is a dead-eye shooter. Derrick White and Dejounte can sometimes be staggered in that role, as Coach Pop did a little bit in the preseason with Tre Jones injured.
Like Samanic, the rise of Tre Jones will have a lot to do with the minutes he gets this season, and that's still up in the air.
