An option in football is play that attacks a specific defender by leaving him unblocked and forcing him to have to defend two different players. One of the players is usually the quarterback and the other is a running back. The quarterback will read the reaction of the defender and either give or keep the ball. The offense has two "options" on the play for who can be the ball carrier. Triple option plays involve a third possible option for the offense.
The defender usually depends on the sport. In soccer (football) the defender is the one that protects the goal. I don't know much about football (American 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.
A pro football because the quarterback is used to throwing the pro football and not a Nerf football.
