THE offense are seen scoring a touchdown. The ball was put in play a yard from the goal line (opposite stake on further side line). The play was directed against the defensive left guard. The left side of the offensive line has been pushed back by the defense, but the right side behind which was the apex of the play is well across the goal line.

The runner (arrow) by a powerful plunge split the primary line of defense but was stopped short by three defensive backs, who now may be seen trying to push him back.

Plays occurring on the goal line always incur a terrific struggle between the opposing lines. Although a heavy back is usually needed to drive the play home, the success of the play depends primarily upon the power superiority of the offensive line.
