I feel like I've made my stance abundantly clear in multiple threads, so I won't spend too much time on it now. In short, the Spurs being patient has nothing to do with finding the right co-star for Wemby. It's because there are no co-stars for Wemby that can alter the team's window besides a handful of top vets like Durant, James, Curry, Leonard and maybe Butler (this is excluding the top-five players who aren't going to be traded). Young, Mitc or whoever else is not going to do anything until Victor becomes a championship centerpiece, and that will take years. Once he's there, the specific differences between those players won't matter. It's like how James won les with a bunch of different co-stars. They have the time to draft players they like and develop them, because Victor's window isn't open yet. Once that changes, then they can make a trade for the co-star, if one is even necessary at that point.
Very little matters besides Victor leveling up. There's basically zero reason to hand-wring about the team during this stretch. There are players who I think could help him do that, but changing the culture of the Spurs, mentoring Wemby are not the same as winning games or having the highest team ratings in 2K. Young, Mitc and Markkanen are basically the exact wrong guys for the team to bring in my mind. If the question is "If not them, who?" then the answer is "Basically anyone else." Besides those aforementioned stars, I would be really interested in Khris Middleton and Paul George, less interested in Gordon Hayward, Robert Covington, Klay Thompson, DeMar DeRozan and Jerami Grant, and even less interested in James Harden, Tobias Harris and D'Angelo Russell. At the same time, drafting and developing players remains a high priority. As I've mentioned before, my ideal rotation (assuming no one major gets cut or traded) would look like this:
First-Round PG, Jones, Wesley
Vassell, Branham, Champagnie
Big Money Vet Wing, Johnson, First-Round Wing
Sochan, RE-Level Vet Defensive Forward, Developmental Forward
Wembanyama, Collins, Min-Level Vet Center
There are other combinations that I think make sense, or course, but paying a bunch of assets and salary space for a PG isn't that high on my personal list.
