re: DK Metcalf tops out at 23.2 MPH on Sunday Night run

I can't believe Ole Miss had him and AJ Brown and did jack shite.

Meh ...40yd times Are meaningless in a 100yd race.
DK clearly has better track speed over the longer distance.

Not really. The initial 40 yards is crucial to the developed speed at terminal velocity. DK is a 4.33 40 runner and just for comparison Bolt ran a 4.22 in an exhibition at the Super Bowl and likely could run low 4.1s in a better situation (he had to pull up at the end due to a short run off).

If he did reach 23.2 mph it really is extraordinary. Especially when you consider the added weight/restriction/air resistance of the pads/uniform/helmet along with the low energy return of the grass, weight/traction of the cleats vs track spikes and the fact he is carrying 25-30 pounds of extra weight compared to a modern sprinter of his height and much of that in comparatively useless upper body mass.

Was it a guy sitting on a chair with a stopwatch? I don’t put much stock into 40 times from way back in the day.

Hand time numbers can be off as much as .5 seconds. The direct comparison era started in 98 or 99 when they started using laser timing at the combine. It is important to note combine numbers do not include reaction time so combine numbers are .25 to .4 seconds faster than a track sprint started with a gun but the track sprinters also are coming out of blocks so it tempers that difference.

They said it was the second fastest recorded speed by a wr..I'd love to know if that's true ,I just dont see that not being the fastest

If you ever watched bolt run a 100 meter race he was rarely in the lead at 40 yds...his acceleration occurs between 60-65 meters and he pulls away in the last 20 meters.

This can not be disbuted.........

Football is won on the lines of scrimmage.

That's not even one of his good ones, but still funny.

He's always on point.

Does this remind anyone of Ben Watson? Bailey pulled up but that was an incredible effort

So...you’re wrong.

Science says I am not.

Nope. Bolt reaches Vmax in the 100 by the 50-53m mark. What you are mistakenly equating to acceleration is the fact he is remarkably efficient at maintaining his speed in the 50-90m portion of the race where almost all other elite sprinters are losing speed, Montgomery and Powell are two that lost less than most. Bolt loses essentially no speed from 50-95m which is unheard of and what made him great.

Science shows that the first 20 meters is by far the most important in 100m final times.* It has the largest negative correlation of any split to the times. Bolt is unusual in that he actually has relatively slow 10 and 20m splits first because in the realm of elite sprinters he has a slow reaction time and coupled with his long levers he is relatively slow to come up to Vmax. He continues to accelerate for about 10 meters longer than the average elite sprinter and again he holds Vmax from 50m to 90+m better than any sprinter ever. If he had 20m splits like Maurice Green he would have run significantly quicker times.

The 10m split is by far the most important in the 100 and by the end of the 40m split almost all the acceleration phase of the race is done. Because Bolt normally has a slow 10m split he is still accelerating through 50m which is not ideal but a product of his lanky body. He absolutely is not accelerating at 60-65m as you suggest he reaches Vmax just after 50m. So... you're wrong.
