I'm guessing around 4.2-4.3 tops if electronically timed. He's a 100m runner and he's still accelerating at the 40-60m marks. That's where guys in the combines would get destroyed by Bolt.
I don't follow football much anymore, but are 40's electronically timed now or are they still using some dodo on the side of the "track" to hand-time them? FYI : Justin Gatlin ran a 4.3-4.4 40 and he was elite-level at the 100m.
LOL DD is drunk and in boast about my past mode. Watch it fella - wine can mess you up way quicker than beer.
In game play he doesn't seem fast but it is because he's so tall and has those long strides. Real smooth on the field.
If you've been following college football for any length of time, you know that college 40 times are notoriously on the low side. Seems like everyone gets bumped at least .1 when they are electronically timed at the NFL combine.
DeAngelo Hall supposedly ran a 4.17 on a college stopwatch. That rumor was obviously enough for Al Davis to sign him to a 70 Million dollar deal last offseason.
He runs a LOT like Matt Jones and they both have very similar build too. Both long legged so while they are not explosively fast or have very good initial quickness give them some room (ie a straight line 40 yard dash) and they can cover a lot of ground in little time once they hit their stride.
They electonrically time 40's at the NFL combine, hand timed is almost always faster. Pryor is fast but I think he's more in the low 4.4's at the fastest.
For one thing, 40 yards is only 36.576 meters, it's not apples to apples to a sprinters splits. Sprinters must wait for the gun and then react which can take .2 seconds, typically football times are started when the player starts. That can be OK with laser timing but is impossibly different for hand timing. Darrell Green, who ran one of the fastest 40-yard dashes ever at 4.09 seconds (unofficially timed and not verified)[1], had a collegiate best of 10.08 s in the 100 meters.[2] Justin Gatlin, who ran 9.85 s for a gold medal at the 2004 Olympic 100 metres, has a verified 40-yard dash best of 4.42 s.[3] This reflects the difference that timing methods can cause to a runner's time. http://en.wikipedia.org/wiki/40-yard_dash So basically, football numbers are laughable crap compared to track numbers.
I wouldn't call running a 10.08 "laughable crap" There have been more than a couple Olympic Runners who went on to sideline as NFL Receivers. Bob Hayes comes to mind.
I'm saying if you put the fastest football player in a lane next to a world class sprinter, it won't be close. The numbers sprinters post are verified and translatable, the numbers you see from football players are usually puff pieces from sports information directors.
