That graph reminded me of the day I was watching my daughter's high school football team practice. I was in my car waiting for my daughter to finish some activity at school that night.
Anyway, the coach was very dissatisfied by the practice and they were running laps. Almost the entire team was running together as a group, just plodding along.
Eventually, I noticed one guy that was ahead of everybody else, that's why i missed him at first. I recognized him as the team's best player, a linebacker. He wasn't plodding, he was giving it everything and he was on the other side of the track still building his lead.
One of the players in the big cluster yelled, "Come back, you are supposed to be our leader!"
The linebacker yelled back from across the track, "I'm in front, aren't I?"
I never heard a purer definition of the word "leader". That's what I think Micah Parsons is.
