My good friend and Mentor, Coach Mike Boyle just put togther an incredible article on the Truth About the NFL Combine 40 Yard Dash Times for his membership site – StrengthCoach.com.

MIke was nice enough to allow me to re-post his article here for your viewing pleasure.
.
There are always great articles on StrenghCoach.com and for a measly $9.95 a month, I don’t know how anyone would not join up for this incredible site. Truthfully, I’m on StrenghCoach.com everyday! Many times just to read and participate in the great forum discussions along with such names as Alywn Cosgrove, Robert Dos Remedios, Charlie Weingroff, Dewey Nielsen to name a few!

Now that I’ve told you how awesome Mike’s Website is, check his eye-opening article revealing the REAL TRUTH about the NFL Combine 40 yard dash times!

The Truth About Speed, NFL Combines and the 40 Yard Dash!
.
Speed is the stuff of urban legend. Deion Sanders supposedly showed up at the NFL Combine, ran a 4.2 and went home. We routinely hear of high school kids who purportedly run 4.3’s and 4.4’s. The stories of “reported” speed have gotten out of control. This would not be a problem in and of itself. Most of us could look at it and say “so what” people lie or people embellish. The real problem is that the lies seem to be setting the standard. One of the reasons that I no longer train athletes for the NFL Combine is the unrealistic expectations of athletes and agents based on these “urban legends” or the occasional freakish performance like Vernon Davis this year.
.
1- Electronic start- electronic finish. This should be the standard but, unfortunately is not. The start is done with a touch pad and the finish with a photocell. This is the most accurate and as a result yields the slowest times. An electronic start/ electronic finish time has been shown to be .22 seconds slower than a hand held 40 yard dash. ( Brown, 2004)
.
2- Hand Start- electronic finish. This is a system used uniquely at the NFL Combine. A hand start-electronic finish will be approximately .1 seconds slower than a hand held 40 yard dash. In the combine the use of hand start will be particularly evident in the faster ten yard dash times. Athletes will run 10 yard times much closer to a hand held but, times at each following split will be closer to the electronic time.
.
3- Hand Start- hand finish- this is the fastest and least accurate. Handheld times tend to be faster but are clearly more prone to human error. Many of the legendary times I believe were hand-held timing combined with human error or human expectation.
.
At the NFL Combine in 1996, 97, 98, 2001 and 2003 and 2006 no one ran a 4.2. No one. Not one person. In 2001 Ladainian Tomlinson ran one 4.36, five in the 4.4’s and vertical jumped 40.5. 2003 was a fast year, yet still produced no 4.2’s. Ten athletes ran 4.3’s in 2003. The heaviest was a 223 pound running back. The Combine track is always said to be slow but the truth is it is simply accurate. All of these supposed fast times seem to be run at times when no independent verification is available. Seems a bit curious doesn’t it.
.
Here’s another angle on the whole “speed” thing. Ben Johnson and Carl Lewis ran split times of 4.67 for 40 meters ( Bryan, Rose-Hulman) The split times are below.
.
1.84 10 yd
2.86 20 (1.02 split)
3.8 30 (.94 split)
4.67 40 (.87 split)
.
40 meters is 43.74 yards. This would make the distance approximately ten percent further. This means we could reduce the time by approximately .36 seconds to account for the additional 3.7 yards. This would mean that in constant acceleration mode the best sprinters in the history of the world, using blocks, ran 4.31 for 40 yards. Does it seem plausible that high school football players can run faster times without blocks.
.
The table below shows some of the athletes who ran below 4.4 at the NFL Combine. Obviously the athletes are getting faster but, we still don’t see the dreaded 4.2’s we hear so much about. In 2005 I believe one athlete actually ran a 4.2 although I did not have those stats available. One athlete in a decade.
.

.
In 2006 of nineteen running backs listed in the internet report (unofficial) Maurice Drew of UCLA was the only 4.3 and he ran a 4.39. In other words one running back ran under 4.4 and, he did it by one one-hundreth. Four wide receivers out of thirty-one ran under 4.4. In fact five ran over 4.6. This means more wide receivers ran over 4.6 than under 4.4. 2006 was an exceptional year for defensive backs with nine sub 4.4’s. The key, again in 2006 was that there were no 4.2’s in the results I saw.
.
As coaches, we need to stop perpetuating the myths. We need to tell our athletes what the average at the NFL Combine was and not what the best “freak” times were. We need to further explain to them that it is unrealistic to expect to even meet the NFL averages. As with everything in our society, we have raised the bar unrealistically high. Let’s be honest with ourselves and with our athletes.
