In my view, Brown and Tatum won't be as good as they were in 2024 again. And White likely won't be either and White was at best the 4th player on that team (Jrue was clearly better and so was KP, he just didn't play enough in the post srason). We saw roughly the same team as the title team just lose in the 2nd round. They need at least 1 more player that is better than Jrue was and Tatum to come back near 100% to have any real shot at competing for a title. They need a high end young player, either to develop or trade for that to happen. I would have traded White because of the Tatum injury and maximized his value. Getting someone like Malauch at 9 and a decent vet in Barrett would have been an excellent return for White and given Boston the first chance at a high end player if Malauch hits. And Barrett for all his faults is still a good player and would have fit fairly well with Tatum (and Brown).
If that trade was made, I probably would have tried to trade Brown to Philly. Something like 3 (Edgecombe), George, and McCain.
So you go into this season with Edgecombe, Simons, Barrett, George, and Malauch. Hope you build some more value into Simons and Barrett or George and then move them during the season for more draft picks and let Edgecombe, Malauch, and McCain get all the minutes they can handle and see if any really hit. Add in the high draft pick in 26, plus whatever you get for Simons, Barrett and/or George. So you enter the summer of 26 with Tatum coming back with Barrett or George next to him plus a more seasoned Edgecombe, Malauch, and McCain, add in the high level rookie and still having PP and Hauser for the bench, plus cap space and some extra assets to acquire a 3rd star player.
That to me was the path to contention the team should have taken.
