Line of scrimmage

Definition and stakes

Fielding Yost Football for Player and Spectator… (1905)

At least six men of the side holding the ball must be on the line of scrimmage. If not more than six men are on the line of scrimmage one man of those not on the scrimmage line must be outside the position occupied by the man on the end of the line. The line of scrimmage is an imaginary line parallel to the goal line and passing through the front point of the ball. A player shall be considered to be on the line of scrimmage if he has his head, his foot, or his hand up to or within one foot of this line. He must also, however, be outside the player next and between him and the snapper-back.

The man who, standing back of his own line of scrimmage receives the ball from one of his own side and then kicks it beyond the line of scrimmage, may not put other men on-side by running ahead of them, nor may he himself get the ball until after it has touched a player of the opposing side.

This cultivates the players in the use of their arms in breaking through an offensive line, and prevents that common fault of going in with head down. The arms must be kept out stiff or the player's head will strike the machine. He must also keep his head up, in order to strike the machine in the right place with his hands. The work also strengthens the legs, arms and backs of the players, providing many of the benefits of actual scrimmage without any of its dangers.
