It's not impossible, with a few GM gymnastics
Trade Horford + Brown + BK pick for Davis.
Package Crowder, Smart, & Morris for a pick
Package Zizic & Guerschon for a 2nd rounder.
Dump their 3 min guys.
Larkin & Baynes are UFA so have cap holds. S&T them along with a 2018 1st for a 2nd rounder (dump move)
Projected cap is 103M
Cap Holds:
Thomas - $6,261,395
Hayward - $32,700,690
Davis - $25,434,263
Tatum - $6,700,800
$71,097,148 committed
Boom - they now have $32 M in cap space ...would Bron take a pay cut?
Sign Thomas over the cap to a max contract using his bird rights. Fill in the roster using draft picks, vet mins, and MLE's
Yes it's Boston and no one wants to see him in Green, but I'd rather see someone take down GS and see him have a chance to win multiple more chips (if not with Cleveland).
