Per KC Johnson of the Chicago Tribune, the Celtics offered the #3, #16, and Crowder for Butler, but were not willing to include AB or Smart.
Would you have done this deal?
At first, this seems like a lot to ask for, but I think we ultimately would've had enough assets to recover from the loss of Crowder and Butler, and assuming Butler might've been enough to convince Durant to sign with us (longshot) this trade would've been more than worth it IMO.
