(j) Mercy Rule: Once the score reaches a 42 point differential, or more, at halftime or any point thereafter, the game will resort to a running clock or will be terminated by mutual agreement.to my understanding a running clock can not ucoure until after half time, but if a coach request it it can, in Murphy v Andrews there was no 40 point Martine and to my understanding there coach ask for a running clock , which they were granted at 28-0 score
