Ryan Day is once again dealing with the consequences of success in college football after leading Ohio State to a national championship.

The departure of defensive coordinator Jim Knowles adds a challenge for Ohio State, which was already dealing with heavy roster turnover on defense.

The Philadelphia native and St. Joseph’s Prep alum will become Penn State ’s next defensive coordinator, according to multiple reports on Sunday. Knowles has been with Ohio State since 2022, and reportedly will be the highest-paid coordinator in college football history. The deal, according to ESPN, is worth $3.1 million over three years.
