To me this trade makes the most sense for a possible Giannis trade, the bucks get their picks back (or NO if they are worse), a young talent in Risacher, and the expiring contracts of KP and Kennard, along with Atlanta's future picks.
Youngs passfirst playstyle should compliment Giannis, and the Hawks would be one of the frontrunners with the assets to acquire him. In a wide open east, this team would easily be a championship frontrunner.
Hawks:
Trae Daniels Johnson Giannis Okongwu
