How Absurd Is A 40 Yard Dash Time?

0.2 seconds over 40 yards is reasonably big though. A guy who runs 4.6 will have ran only 38 yards when the 4.4 guy has run 40. That means on a 40 yard pass the slower corner is 2 yards behind. Say he has to cover a much taller receiver there is no way he can cover the long pass and makes him very easy to exploit.
