The Hawks have so many good role players, that when Hunter and Reddish come back next year, it will be hard to find playing time for them all. I think they really need to consolidate some and upgrade one of the slots. I believe Simmons and his defense would be a great upgrade to a Hawks team that looks ready to contend, and Simmons can stop trying to be the 2nd best player on a contender (which he is not suited to) and instead become an elite role player and defender.

Meanwhile, the Sixers have found that they need shooting and that Simmons just isn't working out. Gallo gives them shooting at the forward and scoring off the bench, and Hunter replaces Simmons for them as a versatile big wing defender, but one who can shoot much better and more willingly than Simmons.

Picks may need to be involved, but I'm not sure which team would have to add picks tbh.
