Réponse :
American football is a collective sport between two teams of eleven players who alternate between defense and attack. The object of the game is to score points by bringing the ball into the opponent's end zone. To retain possession, the attacking team must cover at least 10 yards in 4 attempts
Points can be scored in different ways: by crossing the goal line with the ball, throwing the ball at another player on the other side of the goal line, tackling the ball carrier of the opposing team in his own end zone (safety) or by kicking the ball between the goalposts. The winner is the team with the most points at the end of the match.
