This is basically mandatory in terms of the framework for the deal. Unless Tatum is on the table (he shouldn't be). Brown has to come. Bucks want young talent, Pritchard and Gonzales are about the only ones that comes with any sort of long term control. FRPs come in to match the value, GTJ (assuming he opts in here) is there to give the celtics a chance to rehab what could be a REALLY good rotation piece next to Giannis.
