Top 10 Fastest Players of All Time | NFL Films 

Hines ran 10.03 on cinders in 1964 during the Night of Speed. He ran 9.95 at the 1968 Olympics. The relay legs are not official and were hand timed back in the 1960's.

Bob Hayes was not called, "Bullet Bob" for nothing. He could "prove" that he was the fastest. Look at films of the Olympics sprints.

Bob Hays is the fastest you right

@@johnbarron2269 100%. I saw him play several times as a kid. He was so much faster than everyone on the field it was ridiculous. He ran a a 10.06 100 meters for Olympic gold on a chewed up cinder track. That's well under 10 seconds on today's rubberized tracks. Green was blazing fast, but you can't put him in the same sentence as Bullet Bob.

@@sydboski Bob Hayes always slowed down at the end of the race because he was so far ahead. He had to come from behind in the 4 x 100 so he used all his speed at that time. Bob Hayes never lost a race.

I said the same thing. Except he doesn't belong on the list and neither do 6 others on the list.

That means everyone under Chris should be quicker than 4.24!! This list is bogus

@@elomon3473 You'd be right if the 40 measured how fast these guys run, but it doesn't. The 40 measures quickness and partial acceleration because the really fast guys do not reach top speed til about 50m out. They are still accelerating at the 40yd mark. So the 40 cannot possible determine who is fastest when they aren't even running their fastest now can it? You need a longer distance to where they can get to full speed and maintain it for some time. The 100m dash is the only race that includes all the aspects of total speed. It has start/quickness, acceleration, top speed, and speed endurance (which slows deceleration after top speed is reached). That said, CJ2K's best 100m is 10.66. That 10.66 ranks him 71st all time in NFL history.

@@sydboski It's about football speed. The 40 is ABSOLUTELY a relevant metric on grass / turf. Line of scrimmage at the 30. The fastest guy to 40 yards likely *doesn't get walked down* the rest of the way to the end zone and that's what matters! Here's the measure of speed in the league in my book . . . if a guy got an ounce of daylight on you . . . by shaking you left or right . . . *could he be caught* ? I'm old enough to remember OJ Simpson playing. In OJ got a step on you, the gap just got wider . . . he literally looked like he was walking away from people who were standing still. I saw the same with Michael Vick decades later. And Deion . . . if he found a seam, it WAS A WRAP. Chris Johnson would have been a beast with a longer career. You need to respect that 4.24.

@@gmnewbold1416 1. I never said the 40 wasn't a relevant metric. I said the 40 doesn't measure how fast these guys run. And it doesn't. 2. Show me where it states "football speed". Also tell me how they measure "football speed" in order to compare players not on the same field or from different eras. 3. I saw OJ play also. Yes he was fast but he didn't have Henry Carr, Deion Sanders, Darrell Green, or Terrence Newman chasing him either. There are a lot of player that once they got a step the haven't been caught. Cliff Branch, Mel Gray, Bob Hayes, Jacoby Ford, Lam Jones, Trindon Holliday, Curtis Dickey, Ron Brown just to name a few. There are plenty more. But those are highlights on film. They give you an opinion on how fast these guys are. Unfortunately speed is not an opinion. It is measurable and provable. 4. All of the REAL top 10 fastest players should have a track back ground. No track background? There is no way they should make the list. You cannot just walk on to a track with no sprint training and run world class times. It is physically impossible. It takes years of training to get to world class status. If you don't have world class speed you should not be on the list because you are not faster than a world class sprinter.

When the eagles were at Leigh I seen Vick beat Jackson and Mccoy. and he was up there in age I know Jackson was 4.3 but still has the most over 50 yard tfs and said he ran it bad that team had speed to Maclin was hurt and still did it that's the problem now Daryll Green new he was starter and every time challenged he won like last year shut deoin up 60 yes old 4 6

Yes he made them look like fools

It’s just too bad he was a POS

And while Taysom Hill does not have the moves of Vick, he is faster.

Seriously, those two guys dropped like potato sacks. Wonder if they both had concussions?

Oh well GO BRONCOS

Speed n stick um

Al Davis loved speedsters. His Raider teams also had James Jett, Rocket Ismail, Alexander Wright, Terry McDaniel, James Trapp, and Sam Graddy. Graddy finished 2nd in 100m at the 84’ Olympics behind Carl Lewis, and also won gold in the 4x100 with Carl & Ron Brown. Jett was part of a 4x100 team that won at the Olympics in 92’ and Trapp was an alternate. Wright won a couple of those “NFL’s fastest man” competitions.

I grew up going KC Royals games in 80s. I'd make my Dad get right field seats. Just for Bo Jackson. We had season tix behind 3rd base. I'll NEVER forget him throwing this guy out at 3rd base fr Right Field off his back foot. Ball never touched ground. Glove 2 Glove!!!!!! Guy was out trying stretch a triple out of a 2bager. Whole Stadium was in such awe.

What was super human about it?

@@sydboski either you haven't seen it or you don't know anything about athleticism. The answer is 2 parts, the speed made it superhuman! It's one of the fastest runs in football history!! 2nd, HOF players where amazed & in disbelief of the speed! It takes a superhuman to impress the greatest athletes on earth, which Bo did on this play & his entire career!!

@@bryanelam7431 The speed made it superhuman? It's one of the fastest runs in football history? How fast was he running? How do you know how fast it was compared to Ron Brown out running Darrell Green on a kick off, one of Cliff Branch's long receptions, Trindon Holliday's kick returns, Bob Hayes' receptions or returns, or Tyreek Hill's receptions or returns? All of them were faster than Bo. so please explain that.

@@sydboski I don't think I can because it's impossible to explain things to people that aren't capable of comprehending what they read, which you are! Did I say the fastest, nope, I said one of the fastest & that means more than one!! He isn't the only person to play in the NFL that had world class speed. I don't know exactly how fast that run is & it wasn't times, just like all the plays you mentioned weren't timed either! All that's needed to know that it's crazy fast is to watch it & listen to HOF players that were in the game talk about it!!!

Hill's 100m time 10.19 ranks him 20th in NFL history.

@@sydboski Except for the fact that he ran that 10.19 when he was still in high school. He's much faster now. Try again.

@@sydboski And by the way, even back in high school, Tyreek's 200m time was only 0.36 seconds behind Usain Bolt's Rio Olympics time. And Tyreek's high school 100m time is only 0.01 second behind Bob Hayes' 100m that he ran in his rookie NFL season. So there's that.

@@Michael_Wehrley No, he isn't faster now. He hasn't run track since being a college sophomore. So that means he is not sprint training anymore. Do you know what happens when you stop training for something? You lose that edge. You definitely don't get better. Guaranteed that Hill, right now, cannot run 10.19 100m, because he is playing football and not training to sprint.

@@sydboski Athletes don't peak in their teens, they peak in their mid 20's. I don't care if he doesn't routinely practice full on sprinting, he's not going to be slower than his high school days, because he's a hard training athlete nonetheless in a position that requires endurance and great speed up to the length of the entire field if need be. He's not a lineman, for God's sake, he's a #1 wide receiver.

We just watched Darrell Green catch Jerry Rice in this video.

@@jackjackson721 he caught tony dorsett

33:46

Deions fastest time in the 100 meters was 10.36. Bob Hayes would have blown him out of the stadium

Christopher Hill Madden had to make him that fast otherwise his character would not be good. Hester's best 100m was 10.62. The slowest 100m time for the REAL NFL top 10 fastest of all time is #10 Willie Gault who ran a 10.10. Biiiig difference! You can't judge real life speed from a video game.

sydboski tell em

I'm trying to. But these video game junkies think because they are fast in the game that they are fast in real life.

Well I assume this is talking both real life speed and game speed, two big differences. Go watch Devin Hester highlight video, and tell me that isn't one of the fastest actual game speed players ever.

@@XBillyMexicoX Watching highlights only proves how fast someone is compared to the players on the field at that time. You cannot compare them to players who are from different eras, to say someone is faster or not. On field speed is not accurately measurable. But if you want to look at highlights look at Hester's opening kickoff return in the Superbowl. You will see #43 Colt's safety Matt Giordano run Hester down from behind. Hester never had world class speed. But there have been 25+ world class sprinters that have played in the NFL. All of them were faster than Hester on and off the field.

Yea..Bo was a bad bad man...

Just not the fastest. He really should not be on this list.

Ok Barry Sanders is the greatest running back of all time but one thing he lacked was speed he would always get fetched

@Torrence Johnson yeah he would've

Barry Sanders is nothing more than a quitter! He left his team in training camp & not man enough to them. He sent his daddy to tell them.

@@two869 Yeah, check the stats mehn. Emmitts the greatest.

Barry Sanders isn't close to making it on this list. But he is still the best back ever.

So you didn't watch Darrell Green?

Deion was fast but never ran in the fastest man contest because he couldn't let that perception leave folk minds. He was fast but wasn't the fastest as John Madden would say sometimes.

@@TB-tp2dh He did run in the Superstars competition and was beaten by Flipper Anderson in the 100yd dash.

He was fun though

@@russellnotestine6436 loved watching him on sundays!

Morgan was fast but there are no numbers on him

@@sydboski i wonder if they ever clocked his .40, or if that number survived. Hos 19.2 yds/catch is amazing since he played till age 35. No one in NFL history has as high a yds per catch number while gaining over 10,000 career yards.

Its likely with increased stretching, muscle technology, nutrition etc. that athletes back then didn't supplement their natural speed thus today's guys have better .40 times. But if Morgan had played today he'd be a first ballot HOF. Most of that 19+ ypc was air yards too, and not yac inflated

Ironic you should mention Stanley Morgan, his son plays for the Bengals...who had an awesome WR named Issac Curtis who, along with Stanley Morgan should be in the HOF and Curtis should be on this list ! No DB could cover Curtis, if they threw the ball as often back in the 1970's as they do now, Curtis and Morgan would have some mind boggling numbers. I tell you another guy that I think should be on here...Roger Carr. WR for Baltimore Colts when Bert Jones was QB. Unfortunately neither could stay healthy....but when he was right, Carr was as fast as anyone in the league.

Tyreek Hill what?

@@sydboski #1

@@RAID3R63 I can name 19 players who have run faster than Hill. So how could he be #1?

John ross is faster

@@keyanrusso9265 Sorry, but no. Ross is not faster than Hill. You must be thinking about the lame 40 yard dash which does not measure how fast these guys run. it only measures quickness and partial acceleration because the really fast runners don't reach top speed till about 50m out. So the 40 cannot possibly determine how fast they run if they are not running their fastest. The 100m dash is the true test of speed. That said, Ross' best 100m is 10.66 and Hill's best is 10.19. It's not even close. Hill destroys Ross.

They dont even have Tyreek Hill or John Ross, this isnt even close to accurate

If he never did that stuff, he could have been hall of fame by now. I doubt he would still be playing now but Brady played over 20 years so maybe Vick could’ve stayed healthy and ran a 4.3 at 43

Geez, Al wasn't even faster than Gump. Lol.

Still to this day... The Fastest QB In NFL History

4.25

brandon banks

For one, fast in pads is not the same as fast at the combine. Two, you only get what 3 chances to run the 40 at the combine? Not everyone is going to clock their fastest speed. most don't even care to. Three, some of the players didn't even have measured 40 times in their day. Four, the forty is really for acceleration not speed, most people have to run a little longer to actually reach their top speed. I could go on but I think you get the point.

This is about speed only I would say. Cause how many of these guys are legends? Or hall of famers? Not many or any.

Dude Bo ran his 40 in 4.13 and was 30lbs heavier then Chris Johnson. Yall should be asking yourself how the hell is Bo @ #5!?

If the run was hand-timed you can add between 0.22 and 0.26 seconds depending on if it was an experienced or novice coach.

Anthony Funches That time wasn't official

Same

Anthony Funches In that game vs Seattle Brian Bosworth was chasing Bo Jackson one question WHY??????

Matthew Littlejohn Darrell Green was said to have ran a 4.08!!!!!!!

I can't wait till they come up with some actual parameters and metrics to let us know how they rank the players.

Looks can be deceiving. Branch is my favorite receiver of all time. Branch ran a hand timed 10.00 100m. Which converts to 10.24 fully automatic timing. 10.24 would actually rank him 4th on this list if it went by actual measured speed. Behind only Hayes 10.06, Green 10.08, and Gault 10.10. But there are players who have run faster than all of these guys that are not even on the list.

Jim hines ran in much better conditions than Bob Hayes. And being honest, Jim Hines trained more.

@@berbanedash7935 Hines ran 10.03 on a 40yr old cinder track at the 1968 AAU champs in Sacramento. Hayes ran 10.06 on a 6yr old Olympic caliber cinder track in 1964.

Zach Javaherian bruh I was just thinking that lmao I had to come bacc to this video

Damn right. Hardman is jogging right along with him too.

Hester was not blazing fast. He was quick with very good vision.

sydboski Are you serious? I am a Miami Hurricane fan (Season Tix Holder) so i had the luxury of watching Hester a few years before His NFL career. i have never seen him caught from behind! Thats all that counts in football!! He was as fast as any of those guys on the football field.

+Danny Canes Yes I am dead serious. You've never seen him caught from behind? Here look at this video: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-MVT91mNMS8A.html #43 from the Colts is Matt Giardano he ran 4.48 in the 40. But was a 400m champion in HS. Your boy Hester ran 4.41 in the 40 and 10.61 in the 100m. Very good speed, but not top ten worthy. Just because you never saw him caught from behind doesn't mean he should be in the top 10 all time. There have been a lot of players you haven't seen caught from behind, do they belong? Does Giardano belong? I certainly hope not. To break into the NFL's top ten fastest players of all time you would need to be a world class sprinter, and run faster than 10.10 100m. Willie Gault and Gerald Tinker are tied for 10th place on the all time 100m list.

Wydog Studios DJax only ran 10.5 reportedly. Not in the top 10.

Looks can be deceiving. That's why speed is not an opinion, it is measurable. You really can't accurately judge a person's speed by just looking at them or watching them run. Everything you see them do is based on the others running with them. DJax running away from a 10.7 DB looks the same as Jerry Rice running away from even slower DB's. What some people call "the eye test" is not close to being exact.

No you are not. And Branch did not win the NCAA champs either.

1. Because this list is BS 2. Because Hester is not in the top 30 fastest players by actual measured speed.

Nobody was faster than Bob Hayes! He won 100 meter GOLD MEDAL!

A lot of track stars become NFL players, and I'm sure the 100 meter players are pretty close in speed, and possibly get faster, with training, but most are never that great, but when your on a great team that can blow open holes, Olympic 100 meter speed from any era will be great,
