New trade idea that is a variation of others mentioned. It's massive and unrealistic, but I think each team would be happy with the result.
Celtics trade Jaylen Brown, Jrue Holliday, 28th pick
Celtics receive Reed Shepherd, Jalen Johnson, Jabari Smith Jr., 13th pick
This is a complete retool of the Cs roster, bringing in multiple young effective players on rookie or solid contracts. They keep Zinger until his value recovers, and they try to trade him at the deadline for another player. The future is White-Pritchard-Johnson-Smith-Shepherd-Tatum
Hawks receive Jaylen Brown
Hawks trade Jalen Johnson, Terrance Mann, 13th overall pick
Brown goes back to his hometown. The core of Brown-Young-Risachar-Okongwu is pretty dangerous.
Rockets trade Shepherd, Smith Jr., Green, Sengun, 10th pick
Rockets receive Giannis and Jrue
The Rockets keep all their veterans to make a play on the championship next year. They start Brooks-Jrue-FVV-Giannis-Adams (resigned). And in this trade option, they keep Thompson as a key piece for the future.
Bucks trade Giannis
Bucks receive Sengun, Green, 10th pick
Getting two, highly effective, young players on a really good contracts allows them to retool quickly and look to the future.
Nets trade nothing
Nets receive Terrance Mann, 28th pick
Nets get a solid guard and a pick for their trouble since Mann has 3 years left in his contract.
