Who says no in this trade scenario? (The trade works after the Duncan Robinson S&T)

Warriors move a player they dont want (Kuminga) and a second for their starter stretch center. Vucecic played at a very high player last year and can help them a lot as a win now team.

Heat get even younger by adding Kuminga who has been very disappointing, but he is still very young and can become a very good starter in the right pplace. Miami will be a very young team that will allow him to have a more prominent role and their developmental staff can help him reach his potential. They also find a young replacement for Duncan

Lakers get two 3&d wings who are very good fits with Luka and Bron as versatile defenders who can guard multipple positions, adding the Ayton signing, Lakers are back into contention.

Bulls get a second round pick and two younger players (than Vucevic) that can contribute in the rotation or can be moved for even more assets since both could have value as expirings. I think this is good return for an older Vuc who does not fit the team timeline and is not going to return after the season.
