Being a player-coach carries so many more responsibilities than it did 40 years ago. Interviews, pre-game media, post-game media to start. When it comes to the game how can LeBron communicate with his staff to make immediate decisions when he’s running up and down the floor? Replay reviews, substitution patterns, switching defenses every other time down the floor. I think it’s pretty same to say that we will never see another official player-coach in the NBA, or any professional league for that matter, again.
