In under five seconds, an NFL prospect’s draft stock can either soar or tank. A tenth of a second makes all the difference.
The 40-yard dash is what everyone tunes into at the NFL Scouting Combine. Players have jumped from third-round projections to first-round picks by posting blazing times. Others have watched their stock drop.
Why 40 Yards?
But where does the 40-yard dash actually come from? An NFL field spans 100 yards between goal lines. Why not test players at 50 yards? Or 25?
Most players — outside of wide receivers and cornerbacks — rarely run 40 yards in a straight line during actual game situations anyway.
The answer traces back to one of football’s most legendary coaches.
Paul Brown created the 40-yard dash.
I’d never stopped to question why the distance is specifically 40 yards. It always seemed reasonable, and it’s been that way my entire life.
The Paul Brown Connection
Former NFL employee Anand Nanduri shared the drill’s origins, and they make complete sense.
Do you know why we run the 40 yard dash? Not 10, not 100, but 40?
Before we had a draft, teams would just sign college all-Americans. The small school kids might be able to play, but how do we standardize how fast they are? Paul Brown estimated that on average, a punt travels…— Anand Nanduri (@NanduriNFL) March 2, 2026
Before the NFL Draft existed in the 1930s, teams could sign whoever they wanted. The draft changed that — teams needed a standardized way to evaluate small-school players against prospects from major programs.
Brown, the legendary Cleveland Browns head coach (the team’s literally named after him), figured out that the average punt traveled about 40 yards downfield in roughly 4.5 seconds. He used the 40-yard dash to identify which players would be the best gunners on punt coverage.
Gil Brandt took the drill from Brown decades later. The two-time Super Bowl-winning scout for the Dallas Cowboys helped create the first combine in 1982, and the 40-yard dash was among the event’s original tests.
It’s been a staple ever since.
Brown probably never imagined players would eventually run in the 4.3s, much less the 4.2s we see almost every year now. What started as a way to evaluate punt coverage ability has become the most scrutinized test of every young football player’s career.
