NFL rules and regulations

The NFL is a football league where two teams of 11 players compete to score points by advancing the ball into the opponent’s end zone. The game is played in four 15-minute quarters, with the team having possession trying to move the ball 10 yards in four plays to earn a new set of four. If they fail, the opposing team gets the ball. Points are scored through touchdowns (6 points), field goals (3), extra points, and safeties (2). The game features rules on player conduct, penalties for infractions, and specific regulations on equipment and gameplay to ensure safety and fairness.
