Defensive notebook: How stopping the run led to Iowa turnovers, Buckeyes points

COLUMBUS — Want a tale of two halves? Look at Ohio State in its dominant win over Iowa on Saturday afternoon. In the first half, the Buckeyes turned the ball over twice and were stuffed on a fourth-and-short run that gave the ball back to Iowa a third time. It was a seven-point game at the halftime break. Game on. In the second half, Ohio State forced three turnovers and used them all to completely crush the Hawkeyes. The Buckeyes stopped the run the entire game; Heisman hopeful running back Kaleb Johnson had 85 yards on 15 carries -- 28 of them came on a touchdown run against the second-team defense. Jim Knowles' unit forced Iowa into passing situations, a recipe for a Hawkeyes disaster. It was a Hawkeyes disaster. Because once Ohio State took a two-score lead on the first drive of the second half, it was able to rush Cade McNamara off the edge as Iowa began throwing the ball more.
