Theo Riddick is Notre Dame's smallest running back but Brigham Young learned he's got no shortage of power. The 5-foot-11, 200-pound Riddick ran for a career-high 143 yards against a Cougars defense that entered the game third in the nation against the rush. More importantly, Riddick sparked a ground game that rushed for 270 yards, with his housemate, Cierre Wood, getting 114 yards and George Atkinson III scoring the go-ahead touchdown as the Irish rallied for a 17-14 win Saturday.
