With his team a little stunned after giving up a 75-yard punt return for a touchdown, Penn State coach Bill O'Brien walked up and down the sideline giving players a pep talk. After everything they've been through over the past year, these Nittany Lions weren't going to be denied, even after trailing by 11 going into the fourth quarter. Quarterback Matt McGloin had the go-ahead score on a 5-yard touchdown run with 2:37 left, one of three fourth-quarter scores for Penn State, and the Nittany Lions stormed past No. 24 Northwestern 39-28 on Saturday.
