In American football, the penalty for a "safety" is awarded when the offensive team is tackled within its own end zone, resulting in two points scored for the defensive team. Additionally, the team that scores a safety also gains possession of the ball, leading to a free kick from the 20-yard line. This play is significant in the game, as safeties not only add points but can also shift the momentum. The strategic implications of safeties can impact a team's overall performance throughout the match.
