why not make lebron be the coach. test his competence because he is always arguing with the coach thinking that he is better. let him feel when his players lost respect to him when he manifests incompetence during crunch time.
Lebron would be a great coach and he does get alot of coaches fired but who cares he knows he has power and he uses it. Would u rather them bring back darvin ham? And its not just lebron, bucks got rid of mike b and suns got rid of vogel
