Penn State made the hiring of new defensive coordinator Jim Knowles official on Monday. Here's what each had to say about the move

After Michigan football ran, ran again, and ran some more against rival Ohio State in 2021, Ryan Day recognized that he needed to make something of a drastic change. Out was longtime OSU staffer Kerry Coombs as the defensive coordinator, and in was Oklahoma State DC Jim Knowles.

Knowles, a Philadelphia native with strong ties to the Northeast, transformed the Buckeyes' defense during an impressive three-year stint. Ohio State ranked top three in total defense each of the past two seasons and led the nation by holding opponents to 254.6 yards per game and 4.2 yards per play during a historic campaign.

The Nittany Lions reportedly made the former Ohio State assistant college football's highest-paid defensive coordinator.

James Franklin and new Penn State defensive coordinator Jim Knowles released statements after Knowles was hired on Monday.

The former Ohio State and Oklahoma State defensive coordinator has accepted a job at Penn State, according to Griffin Media's Toby Rowland.
