We got a new HS FB coach my Soph year. He was prob late 20's, carrying prob 20 extra lbs or so. He played CB at a D1 school. Apparently he ran a 4.5 forty "back in the day". It is amazing the diff between a 4.5, prob 4.7ish at this point, and average athletes. He absolutely ran circles around us. It was laughable.
