There are three shuttles, two jumps, the bench press, a 10-, a 20- and a 40-yard dash. Measurements are taken for height, weight, arm length, hand span, front shoulder, back shoulder, back, hamstrings, groin, even intelligence.
And that's just a small part of what NFL prospects are subjected to at the scouting combine.
Some tests mean more to players than others, depending on the position they play. Here are some of the things veteran NFL scouts look for from players at each position at the combine.
The traditional markers of athletic ability like the 40-yard dash, vertical jump and bench press mean virtually nothing to quarterbacks. Tom Brady ran a 5.28-second 40 at the 2000 combine. Unless a quarterback has a 40 time that's off the charts — a sub-4.4 or a time slower than 5.3 — scouts pay little attention.
Instead, scouts like to see the quarterbacks throwing side by side. It's a good way to gauge arm strength and touch. They also rely on a machine to measure velocity of throws.
