Jim Knowles was introduced as Penn State's defensive coordinator on Tuesday. Here's what he said about leaving Ohio State football.

When Allen was calling plays from up top, it was analyst (and quasi-linebackers coach) Dan Connor who relayed calls in to Kobe King. It’s unclear if Knowles, Connor or someone else will have that responsibility on game days.

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 $3.1 million. Knowles is a Philadelphia native. In a statement, Knowles said he was "excited for this opportunity" to join the Nittany Lions' program.
