Former LSU running Back Leonard Fournette came to the NFL with a reputation as that rare combination of speed and power, a reputation that was built on leaving collegiate opponents grabbing at air or flat on their backs. But after Fournette's recent 90 yard TD scamper against Pittsburgh, a run in which he was pulling away from the fastest players on the field, a lot of fans wanted to know, how fast Leonard going? You know, in miles per hour.

The answer is, Leonard Fournette was running at a speed of 22.05 miles per hour. And, according to the NFL, that answer is rooted in science! From the sports / science website

"The NFL began inserting GPS trackers inside every player's shoulder pads prior to the 2015 season. The trackers collect data on velocity, distance traveled and proximity to opposing players. Ever since the introduction of this technology, STACK's been keeping an eye out for impressive numbers. Dating back to to the start of the 2015 season, only one NFL ball carrier has ever clocked a speed faster than Fournette's 22.05  mph. (In a game last season) Tyreek Hill of the Kansas City Chiefs was clocked at 23.24."

And the New Orleans native says he's just rounding back into form, saying he was faster when he was at LSU. Describing his 90 yard jaunt, Fournette told ESPN:

"I ran faster than that in college. It's all about getting my legs back under me. I ran, like, 23 mph in college, so I'm just trying to get my old speed back."
