Lebron gets a lot of hate for his comments which I guess is understandable, but think of it like this. For the past 3 seasons, he has played almost every game of the regular season playing about 38 minutes, then about
43+ minutes in the playoffs where he gets to the finals each year. Add the Olympics from last summer and its easy to see why this guys tired. However, it's not just the minutes. Not even Jordan had to do as much for his team as this guy does, Lebron is literally his teams best scorer, passer, rebounder, and defensive player. That's unheard of and he's had to shoulder the load an unfair amount this year, especially in the playoffs
