Boston get a similar player too smart in Tyrese, who is a lot younger and more consistent, they also get back Delon who would play backup PG (Assuming schroder is traded)

The kings get back a young wing in Cam Reddish along with a pick that could be good in this years draft, seeing as the Celtics are currently 10th

The hawks get what they currently need, a guard who can play defense next to Trae, they also get a future first (Don't know if that is too much)
