We're still so early in the season that single games can swing stats by a ton. For example, Collins and Wemby basically switched places in on-off/plus-minus stats just off last night's match. It's going to take five to seven more games for the stats to start to settle, and we'll have to get up to about the quarter mark before they become large enough to do any math with. The guy in the video is using one game where the Spurs played well below expectations for a half and then made a run in the second half to extrapolate trends. Last year, Sochan was Wemby's third most successful pairing. Last year, Wemby's worst partner was Wesley -- this year it's third-best. Things are very unstable.
Yes, there are real point of concern. The Spurs have collected too many players who are bad AND reluctant shooters, and that's making the decent shooters with high variance look worse their their down games. That's not defensible.
However, I do think it's overblown. Paul and Barnes are both shooting well this year, and Champ is probably the best they're going to get until Vassell comes back. Once Devin is back, it should be good shooting. The swing factor is going to be if Sochan is cross-guarded like he was in the games prior to last night. I think it's very irresponsible to take last night's game as a referendum on spacing rather than the difference between Victor being guarded by Kessler rather than Brooks and Williams. In those other games, Sochan was pulling the opposing center out of the paint with his movement. That was undeniably a positive move for spacing, but Victor struggled against guys who could defend on the perimeter.
The big question is if there's a way to prevent cross-matches without Sochan on the floor. Like would replacing Sochan with Vassell mean the opposing team would be unwilling to put a wing on Wemby? If that does work, then it's possible that a Paul, Vassell, Champagnie, Barnes, Wembanyama lineup really is the way to go. If they're willing to put their center on a forward, though, I'm not sure it'll have the improvement expressed by this video.
This is just a classic example of trying to find a way to blame Victor's struggles on other people so you don't have to acknowledge that he's not ready yet. I'm talking about the video here rather than the OP. Sochan has issues and needs to shape up or be upgraded. But there's no magic that's going to stop games like the second Houston and OKC games from happening.
