The biggest trade rumor involving the Sacramento Kings in the offseason surrounded Jonathan Kuminga leaving the Warriors. It didn't work out, which was probably the best for everyone involved. Kuminga couldn't and wouldn't have changed the Kings' fortunes for the better in the least.
After the now-infamous implosion of the 2024-2025 season, the Kings were expected to make a lot of big moves over the summer to right the ship. They did not. The largest trades were for Dennis Schroder and Dario Saric. Neither acquisition has worked out particularly well for Sacramento.
The big one that never happened was for the Golden State Warriors' Jonathan Kuminga.
