The document outlines the responsibilities of different line judges, field judges, and back judges during American football plays. The line judge is responsible for marking the line of scrimmage, signaling the down to the referee, and moving with the play. The field judge displays the down number, communicates coverage areas to the line judge, and spots the end of the play. The back judge keeps time, displays the down, counts defensive players, and ensures they are not beat by moving players on long plays.
