2. Start Joshua Primo, bench Derrick White
If Popovich really wants to really mix things up, he could decide to start rookie Joshua Primo over Derrick White. White has a history of coming off the bench and is likely better suited leading the second unit rather than just fitting in as a starter. Meanwhile, Primo is starting to get more consistent minutes and, while his play has been mixed, he could benefit from more playing time.
Young players can develop quickly, especially when given time to figure things out on the court. As a result, the Spurs should experiment with starting Primo now and see how he responds. He's already shown a surprising level of poise and confidence despite being the youngest player in the NBA, and a big vote of confidence could really help him going forward.
Thus far, he has shot the ball fairly well from outside, has shown some playmaking ability, and has plenty of defensive potential. Having him start and split time with White at shooting guard could be beneficial to both players and help the Spurs in the long run.
