I think trading Zion is exceptionally hard at the moment. You can’t trade him for a mediocre return in case he proves to be healthy going forward, and the team trading for him isn’t going to give the Pels the AD pick bonanza they are looking for. Are picks allowed to be conditional on playing time or some other measure? Something like every year Zion plays at least X minutes the pick conveyed is a first or a swap, but if he plays less, the pick becomes a second. I know this happens in the NFL, but it’s also substantially easier because there are so many rounds and value is more evenly spread out.
I think NO ends up being an interesting destination for Simmons. They aren’t going anywhere this year, so picking up a guy like Simmons to rebuild value showing he can be an elite player when given the opportunity. A deal for Ingram+ may tempt Morey. He can sell Ingram as a “star” and a team with Embiid, Ingram, and Harris is at least interesting and puts them in the “legit contender if everything goes right” category.
Zion and Simmons is a clumsy fit, but Zion seems unreliable so upgrading from Ingram to Simmons seems worth it from a talent acquisition standpoint. If Zion proves healthy, and Simmons re-establishes his trade value, they can trade one for a better fit. They also have a ton of picks to help facilitate a trade to land a superstar that is a better fit.
