11: Use Wembanyama as an inbounder
This might not be very high on the list of priorities involving Wembanyama, but it could come in handy down the road. During Tim Duncan's time with the Spurs, he developed into a reliable inbounder in pressure situations, and Popovich may use him in a similar fashion in late-game situations. He has shown some ability as a passer, and his height allows him to have a clear view of the floor.
While having him inbound may seem like it would take him out of the play, the opposing center would also be drawn away from the basket, theoretically taking away their rim protector. Also, Wembanyama can hit threes, and the Spurs can run plays in which he gets the ball back after inbounding for an open three. After all, teams tend to focus more on the players on the court, and it may allow Popovich, who is known for his ability to draw up terrific plays out of timeouts, to use some misdirection.
The more of those late-game situations, the better, since it gives the Spurs a chance to see how defenses react to Wembanyama and then respond accordingly. It also helps that San Antonio has Keldon Johnson and Devin Vassell, who made big strides this season and are viable clutch options, keeping opposing teams from honing in too much on Wembanyama. That would seemingly increase the chances of San Antonio trying out Wemby as an inbounder and is definitely something to keep an eye on next season and going forward.
