However, Knowles wasn’t in attendance. About an hour later, reports surfaced that Knowles is leaving Ohio State to serve as Penn State’s next defensive coordinator. The move leaves Day searching for a replacement. Here’s who he might consider as he enters his seventh season as the Buckeyes' head coach.

Penn State football reportedly will make former Ohio State Buckeye Jim Knowles the highest-paid assistant coach in the nation.

Jim Knowles is expected to take the same position at Penn State, as first reported by Yahoo Sports' Ross Dellenger. The two sides are finalizing a three-year deal reportedly worth $3.1 million per season, making him the first college football coordinator to earn an annual salary of at least $3 million.
