It’s NFL Combine time, the time when NFL scouts throw out practically everything they’ve learned about the nation’s top draft prospects and replace it with overhyped, somewhat-useless athletic stats. Sometimes it can come in useful, of course, but if history tells us anything, it’s to not place too much faith in the Combine’s Workout Warriors. Sometimes, all you need is a guy like this.

But in any case, it’s always fun to see young prospects perform well in one or more of the drills. Especially the famed 40-yard dash. Running back Chris Johnson holds the current record, completing the drill in just 4.24 seconds in 2008.

Here’s the video.

Absurdly fast.

To put that in context: CJ ran so fast that it’s comparable with what a Cheetah’s time would be on the same drill. Cheetahs are of course much faster than humans — they can get to a top speed of 60 mph in between three and four seconds, a speed the fastest humans can’t even touch — but over a short 40-yard burst, Johnson was so fast that he can keep relatively close. If we use this Cheetah’s (named Sarah) world record-breaking 5.95 second, 100 meter run as a baseline: At the same rate of acceleration, Sarah would’ve run the 40-yard dash at 2.16 seconds.

One disclaimer: As National Geographic notes, this was a controlled test and Cheetahs often run even faster in the wild, but we’re just trying to give you an ball park estimate.

Here’s the video.

In conclusion: A cheetah would make a very good NFL running back.
