He has more responsibility than any player in NBA history, tbh..
He's the go-to scoring option, the offensive facilitator, the best rebounder and the defensive anchor on the team..going through entire playoff runs in the physical East while playing every single key role on your team is a gruelling task, tbh..
Any player in history would be exhausted in his role, but luckily for them, they haven't had to play his role..
2011 Lebron suffered from the same problem, as is 2013 Lebron at the moment..why was 2012 Lebron an exception? Because it was a shortened season, so playing every role for 2 months less wasn't as taxing on his body, tbh(and why it was arguably the best individual playoff run in history)..
Sucks for him, tbh, as the media is enamoured with scoring production and cliches, while ignoring the other vital aspects of basketball, such as roles..
