Are you trolling? He's absolutely right, the best Wrestlers TEND to be leaders as well. Where are you getting the "aren't actively trying to abuse your teammates on a personal level," nonsense from?
Everyone knows what it means. Lead by example, you're working hard, you're helping the younger kids...just...being a leader. Does every iteration of being a leader need to be spelled out?
And please don't come back with assholes who were great Wrestlers but not leaders. The point was they TEND to be or they usually are. I'll assume Zain, DT, Ruth, Lee, Wrestlers like that have been pretty good leaders.
I'd assume Spencer Lee has been...you watch what he did for his workouts, I'm sure you've got young guys who he's influenced.
