Nothing about our random speculation would make me conclude anything. I think, though, that the Spurs aren't likely to address their true top need (a featured scorer) in the draft. That was much more likely to happen in free agency. I do think getting a forward who can "unlock" Keldon is a possible path forward. He's a negative player right now because of his defense, but I do believe in his scoring potential. Sochan, Eason and maybe even LaRavia could help hide Johnson to allow his strengths to show more easily.
I don't favor the Spurs basically running it back. I'm much more in favor of them aggressively acquiring two players who can be part of a playoff core. I've talked about Lavine, Sexton, Oladipo, John Collins, Jerami Grant, even Julius Randle. Balancing out aggressive moves with solid role-players in the draft is fine. I wouldn't like to see basically the same roster plus four more picks though.
Murray, Jones, A Williams
Primo, Walker, Agbaji, Stewart
Vassell, McDermott, Wieskamp Woodard
Johnson, LaRavia, KBD Landale
Poeltl, Collins, Duren, Ca
That would be a pretty cluttered roster. It wouldn't be untenable, but I'd hope for at least one big trade to get rid of the chaff.
