Dallas
Julius adds much needed playmaking / scoring prowess. Further, Dallas only gives up role players and no draft capital to get a guy who can really elevate their floor and help get them back into the playoffs.
Minnesota
The Wolves get a really nice backup point and another dawg on the wings alongside Ant and Jalen. I don't think they need to blow it up just yet, just lengthen the lineup and clear cap first. Also could be addition by subtraction giving Ju's touches to McDaniels and Naz.
Chicago
The Bulls get a perfect fit, rim-running center to go alongside the Giddey, Matas and Wilson/Boozer core.
