The Harden and Harris contracts expire after the season. Who ever they get in a trade needs to come off the books unless it’s an absolute star (long shot, IMO).
If they trade Embiid for a young star, then that might work as a salary trade, but I also think that’s unlikely. A team acquiring Embiid is in win-now mode. You don’t get better by trading a young star.
So are assuming Philly can convince another alpha dog to sign up to be Joel’s wing man?
