2-13-1 Diagram

2-13-1 Force is the result of energy exerted by a player which provides movement of the ball. A new force may result from a fumble, kick or a backward pass which has been grounded. Force is a factor only when it concerns the goal line and in only one direction - from the field of play into the end zone. On kicks going into R's end zone, force is not a factor since it is a touchback regardless of who supplied the force.
