Actually, with all the shit that has happened over the past few days I am leaning even more strongly toward the Sixers. LeBron wants to effectively be the GM of the team. What better way than getting yourself onto a team that 1. wants you to play for them, and 2. will likely be replacing their President of Basketball Operations in the near future.
The Sixers could easily just hire a guy with a relationship to LeBron and acquire LeBron. As long as LeBron gets his say on team assembly he will be satisfied.
Lakers to me are a non-option. Lonzo isn't good enough and won't be in the next few years. Unless LeBron just wants to play out the rest of his career with 2nd and 3rd round exits in LA, he won't go to a West team that will have to play through both GSW and Houston to make the Finals, unless that West team actually is Houston. I could see him taking a team to beat one of the two. I don't think even his body will hold up from needing to play 44-48 minutes a game at maximum output for 14 straight playoff games though.
