There's always so much made about a player's 40-yard dash time.
That's the old school generic way of determining how a player ranks against others when it comes to who might be the fastest.
The problem with that is a 40-yard dash is it's normally run in shorts at college pro days or the NFL Scouting Combine. It's not truly a fair representation of a player's "game speed," which is the only thing that really matters.
One of the greatest receivers in NFL history, Jerry Rice, reportedly ran a 4.59 40-yard dash before the 1985 draft, and he turned out to be pretty good and didn't have much trouble getting separation for Joe Montana and company.
How fast does a player run in pads with guys chasing him down with the ball in his hands? That's what matters.
On Sunday against the Denver Broncos, the Kansas City Chiefs' rookie fifth-round pick, Tyreek Hill, who reportedly ran a 4.24 40-yard dash at his pro day last Spring, hit a top speed of 22.77 miles per hour during his 86-yard touchdown return midway through the second quarter.
So when it comes to proving who the fastest player is between the white lines, which is all that matters, Hill tops the list, and he spoke after the game about the return that showed his "Cheetah-like" abilities.
"I was just looking at 36 [Broncos Cornerback Kayvon Webster] because he's a playmaker," Hill explained. "So the return was away from him. I set it up towards him and then broke right. I had [fullback Anthony] Sherman and [tight end Demetrius] Harris in front of me. Those guys, big bodies, so ain't nobody getting around them.
"Everybody did a good job blocking."
It was the first touchdown of the game for the Chiefs and came on the ensuing punt following Justin Houston's safety. It gave the Chiefs a 9-0 lead midway through the second quarter.
That return was one of three times Hill found the end zone on Sunday, and each came in a different way.
