Man, let me tell you when I was in high school, I was at 5'9 180 lbs, sub 10% bf. I was fast as fuck, only 1 dude faster than me in my 4A school, anyway, I ran track that year cause I thought I was the shit. There is a huge different between, football speed and track speed. On the football field I was unstoppable, I got on the track and got my black ass smoked. It certainly was a humbling experience. I was in the 1st heat and beat some guys but I was no where close to the top 3 guys.
