This trade is essentially Caruso to San Antonio for Barnes and 2 SRPs, Jones is included to avoid OKC from being hard capped at the first tax apron and San Antonio has options to avoid a hard cap as well. My reasoning for the trade is as follows:

OKC: Trading Caruso for an expiring contract and draft capitol gives Presti some financial flexibility in the summer of 26, it might even be enough to allow him to keep both Hartenstein and Dort as well as pay Chet and J-dub. Barnes also provides some added size and depth in the stretch 4 role and the SRPs will become important in filling out the 2-way player spots. The way I see these spots going forward is a way to develop young prospects with the goal of being able to promote one player each year to the standard roster. As this roster gets more expensive, this will be important for cost control. There is a saying in sports that it is better to trade an player a year to early than a year to late, although this doesn't seem like a big return for Caruso, with the limited minutes that he has played this year the contract extension that he signed could become a bad contract if he doesn't play a lot of minutes next year and he doesn't really have a clear path to extended minutes on OKC next year, so if Presti keeps him, Presti might have to include draft capitol to rid OKC of Caruso's contract in the summer of 26, this trade prevents that. OKC then follows this trade by drafting Maluach with Philly's pick and Fleming with the Clippers pick in the first round of this year's draft. Giving them a single role 3 deep as follows:

SGA/Wallace/Topic Dort/Joe/Mitchell J-dub/Wiggins/Kenrich Holmgren/Barnes/Fleming Hartenstein/J-will/Maluach

With Maluach and Fleming pushing Barnes for depth minutes.

San Antonio: Caruso provides a veteran 3&D perimeter defender that can impact the game on the defensive side especially with a rim protector like Wemby in the paint. He also provides leadership and playoff experience to a young team. Dillon Jones also provides a young talented player that has the potential to be a above average role player on a championship team. All of this only costs them some cap flexibility and 2 SRPs. If they resign Paul and Sandro 2 deep looks as follows next year:

Fox/Paul Castle/Caruso Vassel/Johnson Sochan/Champagnie Wemby/Sandro

Of course they would still have some work to do to fill out the roster. Including 2 FRPs.
