I would trade the 2 Hawks unprotected first, cancel the 2026 swap, the Bulls first and the fake Hornets first for Trae. To match salaries, a combination of Keldon, Tre, Branham, Wesley and Cissoko would be traded.
I agree that a trade for Trae is a huge commitment. It will commit tons of assets, money and will define Spurs' playing style. If it doesn't work, Spurs are quite ed up and it won't be easy to get back on track. At the end, Spurs will only do that move if they're really convinced it will work.
