From 2012-2015, players like Andrew Norwell, Corey Linsley, Taylor Decker, Jacoby Boren, Billy Price, Pat Elflein, Jack Mewhort and my personal favorite Marcus Hall paved the way up front for explosive and balanced Ohio State offenses.
There has been a dip in execution, collectively, over the last three seasons.
Price and Elflein definitely had personal success, winning the Rimington Trophy as the best center in college football in back-to-back seasons. I still think having to move All-Big Ten guards to center the last three years impacted the overall success of the unit.
With four starters gone to graduation or leaving early for the NFL, it is natural to be concerned about the line next year.
