40 yd dash is a joke. Do not understand why so much emphasis is placed on it vs. 10 yard dash, or even 5 yard dash. Burst is way more important than 40 yards of running, at every position, from WR, RB, to DT/G/T Unless you are 2009 CJ, most players will rarely be running 40 yards, full speed ahead. Take for example, D Heyward-Bey. great straight line runner.. bad hands and bad route running. 40 yd dash is a pretty horrible indicator of how they will pan out. Why don't we care who is the record holder for the cone shuttle runs, or the short dashes? All of them are equally as pointless in judging who will be an impact player.
