I'd hate to trade away our first marquee FA signing in franchise history within 2 years... but yeah you would make this trade.
Challenge: Can anyone think of a way to make a Davis-To-Boston deal possible WITHOUT having Horford involved? Maybe with a 3-team deal?
Tatum, Brown, Smart, Morris? That would be a tough one to swallow.
As for the OP's trade, I would begrudgingly do it, but only because I love AD. We would then need to count on the very best vet min guys to sign with us and hope for the best from Smart, Rozier, and Brown.
