Best Defense of American Football

A football is an oval-like inflated ball usually made of cowhide or rubber. the team with control of the ball, attempts to advance the ball down the field by running or passing the ball, while the opposing team aims to stop their advance and tries to take control of the ball.
After a touchdown, a team may attempt either an extra-point or a two-point conversion. However, if the team on defense during the first series recovers a fumble and returns it for a touchdown, or returns an interception for a touchdown, the defensive team wins the game.
