When training, preparing, and coaching defensive linemen, it’s important to remember that the American football defensive lineman is one of the more unique athletes on the face of the earth.

In football, a defensive player’s success will depend on whether or not he can position his feet correctly to place himself in the best possible position to make plays. Foot speed is critical for improving athletic performance on the field. If a defensive lineman’s first step is exaggerated or slow, he will lose balance and be driven off the line of scrimmage.
