COMB - Used marks recorded at NFL Combine.

Explanation of drills:

40-Yard Dash
One of the most popular drills is the 40-yard dash. The sprint covers 40 yards and is used to evaluate speed. Although it is a fan favorite, scouts consider the 10- and 20-yard dashes, as well as 20- and 60-yard shuttle runs and cone drills, as measures of a player's agility and speed.

225 Bench Press
A test of strength in which players bench press 225 pounds as many times as possible.

Vertical Jump
Players stand flat-footed in front of a pole that has plastic flags sticking out of it. Players jump from a standing position and try to swat as many of those flags as they can.

Broad Jump
Like the vertical jump, the broad jump is done from a standing position, but this drill measures how far a player can jump and is a standardized test for power.

3-Cone Drill
Players start in a three-point stance in front of three cones that are set up in a triangle or L shape, with each cone five yards apart. They then sprint five yards to one cone, sprint back to the starting cone, and head back to the second cone where they run around it and cut right to the third cone. The players then run a circle around the third cone from the inside to the outside and run around the second cone before returning to the first cone. How the drill translates on the field for each position differs.

Pro Shuttle
The 20-yard shuttle is designed to test lateral speed and coordination. The player starts in a three-point stance. When the whistle blows, the players run five yards to one side, touching the yard line. They then sprints 10 yards in the other direction and again touch the yard line, at which point they sprint back to the yard line they started from.

20-Yard Shuttle
Players run five yards to one side, then back 10 yards and then five yards to the starting point.

Position Specific Drills
Coaches and scouts run the players through drills designed for the players at their position.
