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

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.

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