"In youth, high school and most college games, referees must signal to one another, in order to be on the same page about what down it is.". Am gasit asta, probabil arbitrii semnalau intre ei ce down urmeaza dupa play-ul respectiv in cazul in care offense-ul nu obtinea 10 yarzi, pentru ca era 3rd & 10, parca asa am vazut.
