Celtics want to shed salary. Get Conley that expires with Anfernee Simons clearing $37M off the books, Porzingis expires as well. Celtics get two pick swaps. They also manage to sign NAW that they otherwise would not be able to sign a Free Agent at that price.

Celtics probably could find better packages that involve more draft capital and cheap contracts (i.e. OKC)

Mavs get another 1st round pick that they want, clear positional room for Randle next to AD and Lively. Get young PG prospect.
