Raptors get Giannis and bring in Myles Turner with him for offensive spacing and outside shooting.
Bucks get a solid return of Barrett, Quickley, Poeltl (Might be re-routed later), 3 unprotected 1sts and a swap. Because of the Steiphen rule which prevents teams from trading unprotected 1st round picks in back to back years, the Raptors can offer slightly more draft capital than most team interested in Giannis. That and Toronto likely wanting to take on Turner as well makes them one of the more realistic trade partners for Giannis.
