Iowa had three running backs in Xavier Williams, Nathan McNeil and Braeden Jackson run for more than 100 yards apiece, and the No. 18 Hawkeyes rolled to a 55-0 victory over Northern Iowa on Saturday even without their top running back, Kamari Moulton. Williams had 151 yards and three touchdowns on just six carries, Jackson celebrated his 20th birthday with 125 yards and a TD to go with a 24-yard TD catch, and McNeill had 111 yards and two scores.
