3: The Spurs have more picks than they know what to do with
With more than a dozen first-round picks over the next six years, the Spurs suddenly have more draft capital than they know what to do with. Winning the lottery allows them to select Wembanyama without trading a fortune to move up a few spots in the draft. Instead, they can simply play wait-and-see with their assets.
They have their own pick in 2024, and the Raptors and Hornets owe them their first-rounders that summer. They also have their own first-rounder in 2025, as well as the Hawks and potentially the Bulls pick. The Spurs likely won't use all those selections, but depending on how good they are, they can package those picks together to move up in the lottery.
Trading up would allow them to wisely consolidate their assets, ensuring they don't waste their picks. It would also give them time to see which young players are irreplaceable and which prospects are expendable. Even then, the Spurs would still have all their first-round picks for the foreseeable future, plus Atlanta's two unprotected firsts and a pick swap. San Antonio is well-positioned to build around Wembanyama.
