I can't imagine LeBron not going to LAL, but the funny part now is that it would involve him rejoining all the players he just purged from his team. That makes it possible that some other team might come into play, and while I would probably expect the Clippers or Celtics to be next on his list, I think Philly is a possibility.
The sad part is that I do think we are going to start to see LeBron's drop off, he has a ton of NBA minutes on his body at this point and I really think he might throw it in a 3-4 seasons. He might want Kareem's scoring record, that is really the only thing for him to shoot for (he might get it in 2022 or 2023 if he stays healthy).
