How to Jam The Receiver (Marcus Trufant)

Описание: Defensive Chair:
Before each play, "sit down" in your defensive chair. Knees bent, a slight lean forward with most of your weight on the balls of your feet. Your feet should be a little wider than shoulder-width. Don't place them too far apart or let your arms hang loosely. Keep your hands in a ready position, with your head up seeing the field.

Move Your Feet:
When the ball is snapped, most times the receiver is going to fire out off the line. So it's crucial that you move your feet and match his momentum. Keeping your feet moving will allow you to react quicker to changes in the receiver's direction, and put you in a better position to turn and run with him if need be.

Off-Hand Jam:
When the receiver is close enough to make contact, use your off-hand to give him a quick jolt to the shoulder. Your off-hand is the one opposite to the direction of his route. So if he breaks outside, give him a pop with your inside hand just enough to throw him a little off balance without giving up your body position.

Ruin the Route:
Once you've jammed the receiver at the point of contact, use your hands and body to ride the receiver off his route. But be careful not to grab his jersey or impede his progress directly. That will likely result in an a penalty. The goal is to force the receiver off his desired route, throwing off his timing with the quarterback.
