In a high school game Team A has the ball first and ten on their own 20. A23 runs to B's 20 where B46 yanks him down by the face mask. During the run A65 bocked B56 in the back at B's 35. Since this is a double foul the ball returns to A's 20 for the down to be replayed. This seems like an inequitable solution since B is being rewarded for committing a foul. If B had not committed a face mask the ball would have been first and ten for A from B's 45. Are their othere situations where a team can benefit from committing a double foul?
