Why Chicago does this:
Easy move, slip Zach for a better fit and former teammate of DeMar. His defense and versatility will fit much better with Coby and DeMar.
Why Atlanta does this:
Huerter and Mitchell complement Trae Young much better and they get a first. Atlanta knows that Huerter fits with Young, and Davion is a much stronger on-ball defender than Murray, which they were looking for originally.
Why Sacramento does this:
Trading Barnes opens up opportunities for Keegan Murray. Davion has been a bust and might need a change of scenery. They get a pick back while losing only 1 first for a guy who might be a true star? Sacramento should jump at that.
