Wait till they add LeBron.
I don't know what Lebron is going to do, but I don't think he's going to Philly. You already have Embiid in the paint and Simmons wouldn't be nearly as effective playing off the ball, and I don't think Lebron is going to be content to be a spot up shooter. He needs the ball in his hands.
The SIxers have plenty of talent but it doesn't seem like the right fit for Lebron.
