1.) More Wembanyama at center
Given San Antonio's struggles on both ends of the floor, they could use a jolt, and playing Wembanyama at the five more often might do the trick. Surprisingly, Popovich has only played Wembanyama 19% of his minutes at center so far this season. While starting him at power forward makes sense, given his thin frame, having Wembanyama play center at times with the second unit or to close certain games seems like an obvious thing to try.
Historically, Pop has favored two big-man lineups, so it's not surprising that Collins or Bassey often share the floor with Wemby. But with little working on either end of the floor, it's worth it to see how the Spurs play with Wembanyama at the five. Given how impactful he's been as a rim protector, the Spurs likely couldn't be worse playing him at center alongside Jones, Devin Vassell, Keldon Johnson, and Sochan.
Offensively, the Spurs would likely play faster, with Jones looking to push the pace, and that would hopefully lead to open threes or easy transition buckets for Wembanyama. We've seen those lineups have success against the Suns, but the Spurs have gone away from that, and they should try it again.
