All depends on if it gets them a ring. But they do have a bevy of future picks and swaps also. Some of those swaps could convince a third team to join the trade to lighten the actual players the Spurs send out.
The Spurs own the #2/#14//#38 this year.
They also own a first round swap with ATL next year, their second, Utah's second, NOP/POR (worst of) second, and two other seconds.
In 2027 they own ATL's pick (unprotected) plus swap rights for their second with a few teams.
In 2028 they have swap rights with Boston, and own three seconds.
In 2029 they have their own First and three seconds.
In 2030 first round swap rights with the better of Dal/Min
In 2031 first round swap rights with SAC
