I know, this trade doesn't make any sense for the Bucks, not gaining any young players with quality and a future, receiving bad and almost untradeable contracts, and only a first round pick for Giannis is crazy (just like it was for Luka, but that trade happened) but maybe in a world where Giannis asks to be traded exactly to Denver, forming the most absurd duo in the NBA, and one of the best duos in the history of the league.
Jazz is just there to get the deal done financially.
