Gut feeling, unless PHI makes the ECF this season, Embiid is gone. And it wouldn't surprise me if a team like the Warriors or Heat decided to cash in and add him. Granted, he'll also be 31 by then and probably not the same MVP-caliber of a player (side note, I was stunned to hear Embiid turns 30 soon, like I thought he was just 27-28 years old right now lol)
I think Embiid is just trolling the media at this point. He knows the Sixers don't match up with Bucks/Celtics and probably not the Heat either, and with all the Harden drama + not having a great group behind that (Maxey is great, but only as like a 3rd option IMO and the bench is bad) it's only a matter of time. We'll see if Nick Nurse can make a difference in that group but idk.
