I don't put a whole lot of value in 40 times. For example, I ran a 5 flat 40 in high school. (the way it was timed back then - 5 guys running, 5 coaches timing with a hand held stopwatch) I was never, not once, caught from behind by guys that were 'supposedly' faster than me. In fact, on the vid's, these track stars lost ground on me. And I was carrying the ball high and tight.
