Get Utah involved. We get Collins and ATL 1st. Utah gets Castle and SA gets Fox. FHuerter and Lyles as fillers if needed.
If you get Utah involved I'd ask for Filipowski too. May as well get Cam Johnson while you're at it.
Sac out: De'Aaron Fox, Kevin Huerter
Sac in: John Collins, Cam Johnson, Kyle Filipowski, 2025 FRP from Atlanta
Spurs out: Keldon Johnson, Jeremy Sochan, Stephon Castle, FRPs
Spurs in: De'Aaron Fox
Utah out: John Collins, Kyle Filipowski
Utah in: Stephon Castle, Keldon Johnson
Nets out: Cam Johnson
Nets in: Kevin Huerter, Jeremy Sochan, 2027 FRP from Atlanta
I would still much rather do a three team deal with the Heat that gets the Kings Kel'el Ware and moves Herro to a third team for additional players/picks OR make a deal with Houston for some of their young players, but this trade at least gets the Kings their rumored targets and a lottery pick.
If it ends up being the Spurs I'd also demand our 2031 SRP and the swap rights removed from our FRP just because.
