I have offered a position on the Ohio State football staff to Oklahoma State University defensive coordinator Jim Knowles and he has accepted it. Starting Jan. 2, Knowles will be the Buckeyes’ new defensive coordinator. What is most important at this time is that we put our players in the best position possible to finish this season with a win in the Rose Bowl.
