Pass rush refers to the defensive strategy in American football aimed at applying pressure on the quarterback during a passing play. This involves defensive players, often called defensive linemen or linebackers, attempting to break through the offensive line to disrupt the quarterback's ability to throw the ball effectively. A successful pass rush can lead to various outcomes, such as sacks, hurried throws, or interceptions. Teams often employ different techniques and formations to enhance their pass rush, including blitzing, where additional players are sent to pressure the quarterback, increasing the chances of a defensive playmaking opportunity.
