Why it's so fast

An NFL Combine 40 is a 40-yard sprint from a still start, timed electronically. Lower is faster. Hand times and pro-day times stay off this list.

  1. No running start

    The clock starts from a set position. Acceleration over the first ten yards is most of what separates the fastest times.

  2. The official clock

    The ranked time is the electronic time the NFL posts. A number that flashes on a board and is later revised is not stored as its own row.

This is how the category works. A note written for this entry appears here once it is in the database.

Context

Background

NFL.com's account of John Ross prints the previous Combine record as Chris Johnson at 4.24, set in 2008. ESPN prints Johnson's previous record of 4.24 and says that record was set in 2008. CBS Sports prints Johnson's 4.24 from the 2008 combine.

The ranked figure is 4.24 seconds. Lower is faster. No calendar day is stored. Wikipedia lists a 1999 electronic 4.24 for Rondel Menendez, also spelled Melendez on another page. The surname does not agree and a third independent page was not in hand, so that time is not a row. Johnson is the only 4.24 here and is not labeled tied.
