Jim Knowles was introduced as Penn State’s defensive coordinator in a Tuesday press conference, a little more than a week after news broke that he was leaving Ohio State. Knowles joining Penn State is a big move for both parties.

Jim Knowles said the decision to leave Ohio State and take the same defensive coordinator job at Penn State came down to returning to his home state. Knowles grew up in Philadelphia, though he said during his introductory press conference that Penn State’s campus in rural State College felt like a world away.
