10-5-5 Diagram

9-4-4, 10-5-5 Penalties for roughing the passer are enforced from the dead-ball spot. But not if a change of possession occurs during the down. In the MechaniGram, A1 is roughed as A2 catches the pass. But A2 fumbles and prone B3 recovers. As a result, the 15-yard penalty is enforced from the previous spot and team A is awarded a new series. The enforcement would be the same if the pass was incomplete or if the last run ended behind the line of scrimmage.
