Not sure how realistic this plan is, but heres what I would do.
1. Trade Jrue Holiday to Detroit for Isaiah Stewart, Simone Fonteccio, 2027 MIL 2nd.
2. Trade Kristaps Porzingis to Utah for John Collins (Dannys turn to do us a favor, like McHale). Give Collins a 3 year extension.
3. Trade Sam Hauser to Memphis for 2028 SAC 2nd.
4. Draft Yaxel Lendeborg with the 28th pick. Draft Kam Jones with the 32nd pick.
5. Decline team options on JD Davison & Jordan Walsh
6. Trade Xavier Tillman for literally whatever. Attach a crappy pick if needed.
7. Sign Al Horford to a 2 year minimum deal.
8. Sign Monte Morris and Torrey Craig to vet minimum deals.
9. Bring back Miles Norris on the cheap.
10. *I'll put this one in asterisks since i dont even know if its possible* Sign Bruce Brown with the $14.4 m injured player exception the Celtics may or may not get from Tatum being injured next year. Again, I don't even know if this is possible given the teams financial constraints.
That would give us a roster of
PG: Derrick White , Payton Pritchard , Monte Morris
SG: Bruce Brown Jr. , Baylor Scheierman , Kam Jones
SF: Jaylen Brown , Simone Fonteccio , Torrey Craig
PF: John Collins , Yaxel Lendeborg , Miles Norris
C: Al Horford , Isaiah Stewart , Neemias Queta
I think thats a nice compromise between what fans want and what ownership wants. It keeps us competitive while cutting down costs a bit. I think this is a team that Tatum wouldnt be completely bummed to come back to.
