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.

Knowles would fill the void on Penn State’s staff left by Tom Allen, who accepted the same position with Clemson earlier this month.

Without defensive coordinator Jim Knowles in attendance on a day sources told ESPN's Pete Thamel he was finalizing a deal to join Penn State, Ohio State celebrated its national championship with 30,000 Buckeyes fans on Sunday at Ohio Stadium in Columbus.
