The point guard made just his second start of the season during the team's 109-100 win over the Dallas Mavericks, but led the side with 26 points.
The coach told reporters: "He's always aggressive. He's not going to get a whole lot of rebounds or stop a whole lot of people, but he's going to shoot it. That's what his skill is."
The result leaves the Spurs needing just one win from their remaining fixtures to make sure that they finish top in the Western Conference.
