I think at this point I'd trade Brown, RW3, and one of the Smart/DW/Brogdan trio for a big man and PG.
Something like this might be intriguing.
Boston: KAT, Lamelo Ball, Gordan Hayward
Wolves: Brown, RW3
Hornets: Brogdon, Gallinari, k anderson
Charlotte dumps GH and frees up PG spot for scoot, Minnesota moves on from KAT and gains some great talent. Boston fills biggest holes and runs with
Ball/Smart
DW/PP
JT/GH/hauser
Hortford/GW
KAT/Kornet/Muscala
Alot of versatility and outside shooting on this team. Might look for a bruiser for deep bench. Might need a pick or 2 to move around, but frankly feels fairly even the way it is.
