Boston - Poku, Mann, Garuba, Covington
LA - Brogdon
OKC - Zubac, BOS 24 1st
Seems reasonable for all 3 teams and the Thunder go from 3 to 1.
Boston takes in the exact salary of Brogdon so it doesn't increase.
So post-trade lineup
Starters - White, Brown, Tatum, Zinger, Rob
Rotation - Mann, Pritchard, Hauser, Brisset, Poku, Covington, Horford
Deep Bench - Banton, Garuba, Walsh, Davison (2W), Scrubb (2W)
To Be Cut/Dumped - Kornet, Champagnie, Griffin
A lot more depth and balance to the roster and as I said, salary is the same. If they can find someone to take the last 3 (or perhaps someone like Covington), they'd save money while filling out the roster so that would be a bonus.
