 The origins of the play date to the tenure of John McKay as head coach of the University of Southern California Trojans during the mid-1960s.The popular explanation for the nickname is that in quarters during which USC was headed toward the end zone which contained student seating, the tailback would appear to be running toward the student section at the Los Angeles Memorial Coliseum, where USC played its home games, before cutting upfield.According to others the nickname emerged because when all the blockers were in place to protect the ball carrier it would appear, from the point of view of a defender, that the entire USC student body was leading the play.
