The Sixers have really struggled to put together a team that can shoot the ball well at a high volume-- they've done okay in terms of picking their spots the last couple of years, but not nearly at the volume necessary to de-clog the paint for Embiid and Simmons. And building a team around shooting shooting 3s has been Morey's specialty. They need guard/wing players desperately, and Morey should definitely be able to build that in short order.

And for Morey, it gets him away from the West, where the GSW dynasty stopped him from making the Finals and the LAL new dynasty would certainly seem poised to stop most teams going forward for the next couple of years, at least. The East gives him a good chance to get that "no Finals appearances" chip off his shoulder-- or, at least, a way better chance than the West.

And he'd have a roster with a couple of prime assets in Simmons and Embiid to build around. If you can get actual shooters on the floor around those two, you'd be in really good shape imo. They just haven't been able to do that yet.
