What does the rusher do in flag football?

In flag football, the rusher is responsible for attempting to "sack" the quarterback by pulling their flag before they can throw a pass or hand off the ball. The rusher starts a few yards back from the line of scrimmage and must navigate through blockers to reach the quarterback. Their primary goal is to disrupt the play and force a quick decision from the quarterback, while adhering to any league-specific rules about rushing. Overall, the rusher plays a crucial role in defensive strategies.
