Gridiron play is a type of football that is played on a rectangular field with two teams of 11 players each. The term gridiron play refers to the various plays that can be used in the game, such as trapping, passing, end runs, and quarterback sneaks. Trapping involves blocking an opponent to create a hole for the ball carrier to run through. Passing involves throwing the ball to a teammate. End runs involve running the ball around the end of the line of scrimmage. Quarterback sneaks involve the quarterback running the ball up the middle of the line of scrimmage.
