To send the running mass wedge into the line directly behind lg, very little change is made from that shown in diagram forty-seven except that the play is directed at the guard instead of c.


Running mass wedge directly at the guard.

C and lt force their men back to the right and left respectively, as the ball is snapped; the half-backs dash forward in the lines indicated, and attach themselves to the flanks of lg with the greatest possible force; the ends strike the formation so made, at that same instant, and each grasps fb from the side as he rushes in behind lg with his head down; while rt and qB throw their weight in behind fb as shown in diagram thirteen, and all plunge forward in a mass pressed firmly together.

The success of the play depends upon the formation of a compact mass which continues to hold firmly together after it strikes the line, and in which all push with their whole weight.
