In American football, a first down is a key objective for the offensive team. It occurs when the team advances the ball at least ten yards within four attempts, known as downs. Successfully achieving a first down allows the team to retain possession of the ball and continue their offensive drive toward the end zone. If the offensive team fails to gain ten yards after three attempts, they have the option to attempt a fourth down play or punt the ball to the opposing team. Maintaining possession and achieving first downs is crucial for scoring points in a game.
