Use when the tackle sets directly at you.
• Assume proper stance and alignment
• When ball is snapped, explode out of stance, stepping forward with ballside leg
• Take second step; then on third step, plant ball-side foot and make contact with tackle, putting top of your helmet underneath his chin
• Place hands on tackle’s chest and explosively drive him back into QB

Allen’s advice: Perform this rush with maximum effort. There’s not much technique to it, so make sure you never stop moving your feet, until the quarterback is on the ground.
