After winning the national championship a year ago, the Ohio State football team had to figure out a way to replace defensive coordinator Jim Knowles. Knowles decided to leave the Buckeyes despite the fact that they wanted to sign him to a contract extension.
Knowles eventually landed with Penn State and became the highest-paid defensive coordinator in college football. It hasn't gone well, as the Nittany Lions have lost four straight games, and James Franklin was fired. Now, Knowles has to visit the Shoe as an opponent.
Ryan Day made it clear that he and Knowles aren't exactly friends following his departure.
