Blazers: Sell mattise and Rob Williams for picks and similar contract one of which being only 2 years rather than 3.
Mavericks: really bolster their defense picking up a really solid defensive center in Robert Williams but has really struggled with injuries, a great defender in mattise thybule who can also knock down a couple 3s and a starting level 4 in Isiah Stewart who can catch lobs, take shoot high 30s from 3 and play defense.
Pistons: get a young 3 and D wing and a solid veteran backup who can catch lobs.
(Really interested to see what people thing mattise and rob williams trade value is because frankly I have no idea, I know Williams is a really valuable player but he could be a shell of his former self by next season)
