Here’s a round-up of the latest news pertinent to Ohio State’s defensive coordinator search. Former Wisconsin defensive coordinator — and interim head coach (2022) — Jim Leonhard seems to be staying put in the NFL.

Ohio State has lost its defensive coordinator to a Big Ten rival. Penn State announced Monday it had hired Jim Knowles as its defensive coordinator. According to multiple reports, Knowles reached a three-year contract with an average annual salary of $3.

It appears that Knowles didn't take long to shuck his scarlet red colors and put on the blue and white at Penn State, taking aim at the conference leaders. It's a huge get for Penn State, who already had one of the most productive defenses in the nation last year, and now adds arguably the top defensive coordinator in the sport to the mix in 2025.
