Besides Jimmy, I don't know if a legit fit is out there. DeRozan back in 2018 had the talent to help Wemby and Vassell, but he's slowed down and is basically a post-up guy now who lacks the size of older Rudy Gay. Klay's resume looks good, and he's probably obtainable, but he's definitely on the downside and never really exuded the same aura of excellence as Steph does. If the Spurs had cap space (yes,
objective, it's okay to bring up Collins' contract if you want), signing Thompson outright for a two-year deal might be the best they could do. But then you have to deal with the fact that Thompson basically plays the exact same position as Vassell.
As weird as it may sound, maybe Jerami Grant? Dude's never been a full-star, but he has been in a lot of situations and has experience cutting his teeth to go from second-round afterthought to key role-player, to lesser star. He's due big money and probably isn't worth it to anyone. But he does round out the roster pretty well (can slide in as a 2B next to Devin and bolster the forward rotation with Sochan) and is cheaper than a lot of other stars. He also doesn't turn 30 until next month, so there's meat left on that bone. It would be a gamble, but depending on who would go out as part of the trade, it might not be that risky. He probably gives off Hawks/Nuggets-Millsap vibes more than anyone else in the league right now.
