Rough Estimate of Denard's Speed

Submitted by imdeng on
We have several data points regarding Denard's speed - 40 yard times, 100m sprint times etc. However, we do not yet know how fast Denard is in a football game - with all the gear on and the ball in hand. Now, thanks to the 83 yard TD run - much of which was a straight line sprint - we can do a rough estimation of Denard's football sprint. I am basing this on one of the several videos of the TD run. In that Denard shoots through the gap and starts sprinting at the 20 yard line at the 8 second mark and then crosses the goal line at the 17 second mark - so roughly 9 seconds for 80 yards. This yields a speed of 4.5 sec for 40 yards in game situation. Thats pretty fast - and that too after running around for almost two quarters - I guess he would have been faster when not tired.

Your average 40 time is going to be faster over 80 yards because you only have to accelerate once.  In a short run like 80 yards, this is probably more influential than the slowdown in the second 40 meters due to fatigue.

But when you instantly accelerate to full speed like dilithium, maybe this doesn't matter.

40 yd / 4.5 sec = 8.88889 yards/second.

This is 18.1818 miles/hour.

Which is 67% of Usain Bolt (~27mph) with full pads, running in Notre Dame's grass.

Nice.

The Dilithium released during a full speed run by Denard actually causes time to slow down which would  skew your results and also make recording his actual speed impossible.Some interstellar warp speed law of physics.  Thats why that game went to like 7:30

...can never be equated to track speed, naturally. The main reason is that you're wearing a few pounds worth of restrictive equipment. You're also not running in a straight line, for the most part. Finally, if you're the ball carrier, you're speed is hampered more by the restrictive arm position. (You can't do the ideal "ear-pocket" sprinter's hand motion.)

Denard outruns the FPS of the camera making it look as if he is teleporting. We see Denard in the endzone and then feel the sonic boom. Outpacing the speed of light Denard grows younger as he sprints.

4.5 in full pads will be the fastest player on the football field every time.     And that, as the OP pointed out, after running around the field for a while and taking hits before the sprint.    That would also mean that he may, in fact, be a little faster than his purported 4.32 forty yard dash without pads.    

It has been a long time since I have a seen a guy consistently outrun the angles the way Denard does.   This guy is simply scary fast!!!

traveling faster than the speed of light enables denard to time travel and therefore he has scored several times by the time we actually view the first.   eventually the refs and scorekeepers will catch up to this and allot us the actual points scored- at which time the natural order of the universe will be restored with us atop the mountain.

Using the game clock limits the precision significantly.

Just going off the game clock, he covered the 80 yards in 9 +/- 1 second.  So he was somewhere between a 4.0 and 5.0 second 40 time.

Mike Hart wasn't fast but he had vision and patience that helps a lot. There are tons of fast guys but track speed doesn't equal success in football. It helps but with out vision and patience, you'll get lucky in a blue moon with a big run. Maycock used the word patience, if I am not mistaken, a few times last Saturday about Denard. And that's the difference between DROB of 09 and DROB of 10.

Man, for me, Denard is fast-enough.  No comparisons, no predictions, no algorithms - just pure speed.  And the beauty of it is humility.  His comment about not getting caught from behind was nice to hear.  Even though he was arguably the fastest on the field he takes nothing for granted and, IMO, always thinks that there could be someone faster.

...Denard has everyone playing tight because they know he's so fast. That makes him even faster than everyone else on the field. Kind of like how Barry Sanders froze people.

I was listening to the Scott Van Pelt show the other day and co-host Ryen Russillo said Jeff Demps from Florida is the fastest player in college football. Van Pelt responded by saying he would like to see Demps and Shoelace race. Either way Denard makes opposing D coordinators have fits and that is good enough.

but Demps would beat him in track because he has actual track training and knows the technique in running sprints.  Denard from what I've seen from him in track, runs with bad techniques and relies on pure speed to make up for his shoddy techniques.  If Denard has the same coaching and training for track, then it'd be a very interesting track meet between the two, hypotehtically that is.

Are you the Oracle?  I  would have thought he would be the only one who could difinitively say that certain result would occur before it ever happened.

Sorry, I may have come off as a bit of an ass there, but I have a hard job imagining it is as simple as" Demps would beat him, no question". They are both incredibly fast, they both run track and I would be interested to see the two race, not that it will ever happen.

ran track in all of his life and ran 6.51 which is world class speed while Denard ran 6.81 last year.  Demps has been trained  to run track for most of his life while Denard isn't.  With proper training, Denard can probably cut it close to 6.5, most likely 6.6.  This is coming from my friend who ran track in college.  He said Denard is fast but not Demps fast.  Denard is fast, simple as that.

is Demps is a track guy playing football and Denard is a football player running track.  Do you understand what I mean by it? 

 

Demps has been coached by professional track coach and has traveled all over the country for track whereas Denard ran track in high school, but is not part of the track circuit.  I'm sure that if Denard devote a lot of time running track like Demps, he could run 6.6 range in 60m.

They just did a segment on ESPN about Chris Johnson's speed and on his long TD run against the Raiders he reached a top speed of 22MPH.  I gotta believe Denard is somehwere close to him, I'd say definitely a solid 20.5 MPH. But then again there isn't a radar gun capable of detecting flashes of dilithium, so we may never find out.
