How about this trade
Brown, Hauser, Tillman, Scheireman
for
Castle, Vassell, Johnson, Carter Bryant, 2027 ATL 1st, remove 2028 swap w/ BOS (maybe another 1st in future as well)
So the rookie of the year, a rookie lotto pick, 2 starter/high rotational level wings, and a future 1st or 2. Plus team drops enough salary that dumping Niang gets Boston out of tax or can move Simons, Vassell, or Johnson to drop salary and get out of tax that way.
