I mean, he's not a center. You need to actually watch him.
You'll still get matchups when you play him along with Collins, which is what will happen. Collins can leave the lane when he needs to. He's a good shooter.
Just as often, Wembanyama will pull out of the lane to let others work. For example, Sochan making attacks at the bucket. This is what he does now. He'll be picking guards or floating away from the action. They're going to move him around a lot.
This isn't Duncan where you're posting him up even 80%. Not at all. Wembanyama is kind of terrible as a post guy and it's not his game, but they'll work on it.
