Projected NBA 40 Yard Dash Times (Being Updated slowly...)

[xxRoyalexx]

A mistake by me. The curve is in fact 0.3-0.5 seconds depending on the weight of the player. I'll correct some of these times shortly.

don't bother. your formula is the fail

You joined last year but you clearly haven't shed off your ballboy tendencies.

I didn't make the formula either. This is from a website regarding sprinting and total fitness. Good try though.

Could you suggest a better one? His formula is actually based off the physics equation d = 1/2 a*t^2. He didn't just pull it out of his ass.

Runners don't accelerate at a constant rate, or an 80-year-old man jogging for a few miles might cause a sonic boom by the end of his run.

Whatever website you found that from is a farce.

If you want to take times more seriously, consider the acceleration in an elite 100-m sprinter like Bolt: http://speedendurance.com/2008/08/22/us ... endurance/. Then keep in mind the average NBA player is less explosive to begin with and that they also don't have the speed stamina of an elite sprinter so they're more likely to taper off.

My guess is the fastest guys in the NBA run low 4.5 ("official/real" time) or high 4.3/mid 4.4 ("NFL scouts" time). I'm talking guys like prime Allen Iverson or Rajon Rondo.

Hence why there's a slight "curve" added to the projected time. It's obvious that an NBA players speed will taper off throughout a run thus making their time far slower, which is what the curve is.

These times look too fast. ESPN broke down Usain Bolt, and his fastest 10 meter (33 feet) split ever was 0.82 seconds. If you're taking Wall's time at 3/4 court (25 yards), you have to add more than 1.15 seconds for Wall to cover those last 15 yards (45 feet). Otherwise you'd have Wall going faster than Bolt.

my suggestion: stop trying to project.

lol at some of these times. evan turner would be lucky to run under a 4.6 i'm sorry. Wall is probably high 4.4

lol cool thread though and you obviously have lots of experience with sports and stuff lol

Remove the word "true" in "true 40 yard dash time" because that makes it sound like you're pulling this data from ACTUAL 40 yard test runs, when your just estimating it off a different length, then adding some extra for error....

If Bolt covers 40 yards in about 3.87 and Wall covers it in 4.25-4.3, I don't see how Wall is going faster than Bolt? I'm pretty sure you're looking at the projected times and not the true ones.

The "True" time obviously isn't true. It is in fact an estimate. It's not based off of a different length, both the projected and true are based off of a 40 yard sprint. The true time is simply the projected time with extra time added based on the weight of the player, to represent the player's speed decelerating as they finish up their run.

The formula sucks. Just becuase Bolt can cover 40 yards in under 4 seconds, doesn't mean his 40 yard dash time is under 4. I would put money on Chris Johnson over Bolt in the 40. In the 100, obviously Bolt would destroy him.

That said, nobody in the NBA can run under a 4.3. I doubt any can run a 4.4.

WHAT? First of all that comment didn't make sense. If you can cover 40 yards in under 40 seconds you can't run a 40 in under 4? What do you think I meant by cover 40 yards?

I hope you know that Bolt and Johnson actually did plan to race eachother for charity at one point in time, and every news outlet across the board agreed that Johnson would get smoked. Bolt's acceleration is simply unmatched.

BTW Rajon Rondo, Nate Robinson and LeBron all ran 4.4's in HS. LeBron sometimes ran a 4.3. Michael Jordan ran a 4.3 in College, so you can gtfo. I provide you with math and facts and you're giving me your opinions. Putting money on someone doesn't make them faster.

BTW, the formula is based on the actual laws of physics. I didn't make it. So if you have a problem with it go question nature and how physics work, not me.

Based on the 10m split times available for Usain Bolt's 100 m race in Berlin, I have Bolt at 4.200 s (using several methods of interpolation), after subtracting reaction time.

For the sake of comparison, Chris Johnson was clocked at 4.24 during his official combine (in which he also didn't have to react to a gun). To be fair, he wasn't wearing cleats on a track surface, but I don't think it makes that much difference. Bolt would still win through 40 yards, and he'd smoke CJ on the back 60.

You're correct that Bolt would beat Johnson over 40 yards, but Coop is correct too because I assume he means he could cover 40 yards in under 4 seconds with a head start. In fact, he hits his top speed around the 70 m mark (0.81 m/s), and actually would cover 40 yards in about 3.00 s based on his time from the 50 m mark to the 90 m mark.

BTW, the formula is based on the actual laws of physics. I didn't make it. So if you have a problem with it go question nature and how physics work, not me.

You're totally botching the use of that formula to the point that it has no validity whatsoever the way you're using it. That's like saying because T-Mac scored 13 points in 35 seconds, he'd score 1070 points in a game.

[Recently]

The fact that by these calculations even factoring in some buffer has Cousins clocking in under 5 seconds should tell you enough.

I don't think you understand how few people are able to run in the 4.2-4.3 range, its pretty rare. NFL athlete are trained specifically for short distances, and train for the combine for months. i find it incredibly hard to believe that basketball players that are both taller (bad for short distance running) and don't run at full sprint nearly as often in their sport would be able to clock in at times better than alot of NFL skill position players.

You can't take a shorter distance and try to add time to it by adjusting it to the average over that period.

HS 40 times are always .2-.3 sec faster than actual.

no one, and i mean NO ONE in the NBA is anywhere near as fast as the top NFL players. they don't have the muscle mass and they're not trained for sprinting. let's just stop with the NBA/NFL comparisons. they make no sense.

this thread = complete fail.

The 0.82s split doesn't refer to Bolt's first 10m, he doesn't hit top speed until around the 50m mark. Bolt wouldn't run a sub-4 40 as he's not at full speed at the start.

But for Wall to go from 3.15s in 25 yds to 4.3s in 40 yds would mean he ran 15 yds (45 feet) in 1.15s. That would put Wall's 10m split at 0.84s. So no faster than Bolt, but only 0.02s behind Bolt's fastest 10m ever.

Wall's fast, but to put him that close to Bolt's peak? I say no way.

This^ I find it funny that this guy came up with his own data and estimation, not factoring the individual's center of gravity, muscle mass, training and sprinting talent. The majority of NFL skilled positional players were at one time or another HS track stars or lettered in track. There are a couple of guys in the NBA who were track stars as well in HS and they are Nate Robinson(hand-timed 4.4 speed @ the University of Washington Huskies football team) and Sonny Weems who both coincidentally posted the fastest times in the history of the combine over the 3/4 court sprint identically @ 2.96 seconds, so your implying that John Wall who ran 3.14 seconds can run the 40 in 4.25 seconds? Then how fast do you think Nate Robinson and Sonny Weems can cover the 40? 4.0-4.1 what a loser The OP failed big-time The Speed of the NFL is close to world class level and is unparalleled amongst all pro-athletes in other sports, this thread like the OP is failure.

[hype_2004]

Decided I'd post this after that thread regarding NBA players in the NFL and whether or not they had the speed.

The Formula:
[acceleration = (2*distance)/(time^2)]
[time = [40/(1/2*acceleration)]^(1/2)]

*These times are not dead on accurate. The rule of thumb is to add about 0.3-0.5 seconds to whatever time I get in these formulas for what'd be their true time. How much I add depends on the weight of the player, something which I just learned recently.

*These are the times of the players from the 2010 Draft Class.

John Wall (6'4", 195lbs)
3/4 Court Sprint: 3.14 seconds
Projected 40 Yard Dash Time: 3.97 seconds
True 40 Yard Dash Time: 4.25-4.3 seconds

DeMarcus Cousins (6'11" 292lbs)
3/4 Court Sprint: 3.55 seconds
Projected 40 Yard Dash Time: 4.48 seconds
True 40 Yard Dash Time: 4.95 seconds

Evan Turner (6'7" 214lbs)
3/4 Court Sprint: 3.27 seconds
Projected 40 Yard Dash Time: 4.14 seconds
True 40 Yard Dash Time: 4.45 seconds

Luke Harangody (6'8" 240lbs)
3/4 Court Sprint: 3.41 seconds
Projected 40 Yard Dash Time: 4.31 seconds
True 40 Yard Dash Time: 4.75 seconds

Derrick Caracter (6'10" 280lbs)
3/4 Court Sprint: 3.61 seconds
Projected 40 Yard Dash Time: 4.6 seconds
True 40 Yard Dash Time: 4.95 seconds

Wesley Johnson (6'7", 206lbs)
3/4 Court Sprint: 3.14 seconds
Projected 40 Yard Dash Time: 3.97 seconds
True 40 Yard Dash Time: 4.25-4.3 seconds

Gordon Hayward (6'8" 211lbs)
3/4 Court Sprint: 3.22 seconds
Projected 40 Yard Dash Time: 4.08 seconds
True 40 Yard Dash Time: 4.4 seconds
Note: Hayward was an incredible tennis player in HS. Tennis players are fast. The speed is nothing to doubt.

BEING UPDATED.......

You want to see just how fast NFL athletes really are well look at what TerrelL Owens did in the superstars competition, where are all the basketball players? There are also a few videos of NFL athletes strutting their stuff over 100 yards, Galloway smoked Olympic decathlete Dan Obrien (legit 10.4 100 meter sprinter) over 100 yards just think what he would do in his prime to a guy like Allen Iverson who is more quick than fast.

Monta said he ran a 4.1

He was referring to his moped running at 4.1's
