Jim Knowles spent three years in Columbus as the defensive coordinator for the Ohio State football team, and the Buckeyes won the national championship in his final year. 

However, it doesn't sound like OSU is going to be rolling out the red carpet when he returns to Ohio Stadium this Saturday. In this episode of the Buckeyes TomOrrow Morning podcast, you'll hear directly from Buckeyes' head coach Ryan Day about the current status of his relationship with Knowles, what he learned from hiring both Knowles and his replacement Matt Patricia, and how the Ohio State defense has actually been better under Patricia than it even was in Knowles' best season.
