Atlanta adds defense and a star-level(ish) player along side Trae. This also drops ATL just under the tax line. Gives them a chance to get back on track with expectations this year with Siakam
Toronto loses Pascal but gains shooting in Gallinari, a young prospect that was highly regarded going into the draft, and two first rounders. They shed salary to get just under the cap with this trade.
OKC eats Dragic's salary and adds a late 1st rounder for Cam, who it doesn't seem like ATL wants to pay next year.
