IT, Bradley, Crowder, Melo and Al is probably as good a starting 5 and any non-Warrior, non-Cavs team in the league. The question is what do we have to send out from the bench? Rozier is a no brainer and Amir almost has to go to make salaries match.
As for picks, there's no way Ainge is giving up the 2017 Nets but the 2018 would probably be in play if it meant keeping Smart instead.
