For KM:
Bradley, Sully, and Boston 2016 1st
OR
Bradley, Jerebko, and Dallas 2016 1st
The thing is, given that GA is probably untouchable, they might be better off trading Jabari than Middleton, because at least Middleton can justifiably play the 2. Jabari isn't a 4, he's a 3. And GA is also a 3 that can't play the 2 long-term. So even if you supplant KM for AB, you still have one of GA or JP playing out of position, though GA might possibly be a long-term smaller 4.
EDIT: Imagine the small-ball that we could play with Middleton - IT, Smart, Middleton, Crowder, Amir or KO. That's more than likely our best defensive lineup (w/ Amir) and offensive lineup (w/KO).
