Timberwolves get deeper, a lead ball handler, and a rim protector who can catch the ball.

Raptors get a defensive center to play over Poeltl. They also get an interesting young player in TSJ

Mavericks get two shooters to put around Flagg. MPJ would work well with him and Gradey Dick needs a change of scenery.

Nets get Randle who can help the younger guards play make. he is also a good play finisher to help the guards. They also get the 28th pick and 2nd rounder. You could add another first round pick from Minnesota or a couple seconds from either three teams.

I see clear benefits for all sides.
