I actually think he'd be very good in the lineup. The issue is that the Spurs don't have a great option for two-guard. If Castle or Harper proves to be a good shooter, they make sense. Otherwise, a pure three-and-D player would be golden. Say the Spurs sign NAW
Fox, Alexander-Walker, Sochan, Durant, Wembanyama
Sochan's basically the center in that lineup, and his job would basically be to be Fox's PnR partner, defend the best front-court player and get rebounds. If he's standing on the perimeter waiting for C&S chances, he's not playing his role properly. I think Jeremy has to learn to shoot well to truly winning player, but his size gives him a couple of avenues to survive as the worst shooter on the floor in a way that Harper and Castle don't have. I've love for one of the Steph or Dylan to take that starting SG role, as learning to be a good role-player is really important to their long-term development. But they're going to have to have those percentages up and show some good defense to get that role.
