Luke Fickell has made his rounds during the Big Ten Media Days, talking about this coming season from the full podium to the individual sitdowns with reporters. In an interview for the Cover 3 podcast, he was asked about the defensive line improvement from last year to this year, and Fickell identified that specifically as the biggest change coming into the year.
It's been an obsession of Fickell's since last year. He called it the breakdown at the end of the season, that the trenches along the defensive line just couldn't hold up. They weren't big enough, and they need to be bigger to compete in Big Ten play.
