The two teams rumored to be shopping their picks are Sacramento (4) and Portland (7). If the Spurs consolidated, maybe 9 and 20 (25 too?) gets them up to 4 or 7. I wouldn't do that for Banchero, I would do it for Ivey and Smith. I'm on the fence on Holmgren. But that is moot. The more relevant questions is would the Spurs consolidate picks for Benedict Mathurin?
A more realistic option includes Keldon Johnson plus draft picks to go to 4 or 7. In these scenarios, I'd prefer to keep 9 and give up a future FRP, which Portland, at least, would likely prefer as they can later package the pick for a win now player. If the Spurs landed 7 and kept 9, there are lots of appealing scenarios where two of Mathurin, Daniels, and Sochan are available to them.
New Orleans is strong candidate to draft Mathurin or Daniels, if either is on the board. Cutting in front of them would give the Spurs the ability to grab the guy they most believed in.
If our rebuild core became Murray (vet leader), Vassel, Primo, Mathurin, and Sochan, fans would have a lot to be excited about, including our 2023 lottery pick. Plus it puts us in a position to have meaningful cap space in a future offseason that isn't such a dud. If we keep Johnson, we're far more constrained.
