How about flip this around some and do a trade along these lines:
Brown + Hauser
for
Zion + Murray + Picks?
NOP keeps their good young player in Murphy, which makes sense they would want to do. BOS gets Zion, a potential upside players with some risk and a vet guard who is actually pretty good. I think NOP would include at least 1 first with this as well.
It adds about $7M to BOS salary, so limits flexibility, but results in a pretty well balanced team:
Murray
White
Tatum
Zion
Queta
