Reading the combine
The NFL Scouting Combine puts draft prospects through a battery of athletic tests: the 40-yard dash, the vertical leap, the broad jump, the 3-cone agility drill, and the 225-pound bench press for reps. Each number tells a small story about speed, explosion, agility, or strength. This tool collapses those separate measurements into a single composite percentile so you can compare athletes at a glance.
How it works
Every drill is mapped to a 0 to 100 percentile against an approximate combine reference range. Higher-is-better events use:
percentile = (value - low) / (high - low) * 100
while lower-is-better events like the 40-yard dash and 3-cone are inverted so that a faster time earns a higher score. For example, a 4.30-second 40 scores near 100 and a 5.30 scores near 0. The composite is simply the average of whichever drills you entered, clamped to the 0 to 100 range, and then mapped to a grade from below average to elite.
Tips and caveats
The most important caveat is that the combine measures athleticism, not football. A defensive back can run a blazing 40 and still struggle to read routes, while a slower receiver with great hands and timing can outproduce flashier testers. Use the per-drill breakdown to spot a prospect’s athletic profile: a high vertical and broad jump signal lower-body explosion, a fast 3-cone signals change-of-direction agility, and bench reps speak to functional strength. Because the tool weights all drills equally, weigh the events that matter most for the position when you interpret the result. Leave any skipped drill blank and it drops out of the average cleanly.
