This is actually a fun experiment.
From what I've read, the Spurs would have taken Miller #2 (I forgot who reported this the other day... might have been Tynan) and that they had Amen over Scoot. This are all great signs for the talent evaluation department that we had started to be concerned about.
So let's say the Spurs got Miller. Let's also assume they still draft Castle, since the Spurs certainly would have still been in position to draft him and all indications are that they had their eyes on him for a long time.
What move do you think the Spurs would have reasonably made differently? I think the only different moves would have been not signing CP3, and probably not trading for Barnes (though maybe, since it still would have netted us assets, though we'd probably be looking to flip Barnes). We probably would have used pick 8... and without Wemby maybe they go for Zach Edey. So I'd feel pretty confident that the lineup today would be something like Castle/Dev/Miller/Sochan/Collins. Maybe Tre in at PG and either Castle or Dev to the bench (probably Castle) and maybe Edey in for Collins. IMO, that team is significantly worse than the team we have right now (though maybe it could be good in the long run, though of course I'd still rather have Wemby).
The team has not shown a willingness to go out and make a big splashy move, and certainly I don't think they would if we had Miller (or Amen) instead of Wemby. If anything, I think Wemby makes us MORE likely to make an uncharacteristic big move.
So, I think it's pretty reasonable (though maybe still wrong) to say that if we didn't land Wemby, we'd still be pretty bad and probably looking towards the 2025 draft as the opportunity to get our Superstar to pair next to our other young guns in Dev/Sochan/Miller/Castle/Edey. If we have a long term view... that actually wouldn't be that bad of a place to be. Flagg, Harper or Egor added to those 5 might be pretty fun (and I think they all generally fit... if anything, Devin probably is the one who fits the least just from a timeline POV).
