Urban Meyer and his Ohio State Buckeyes were able to finish the 2012 season without losing a single game.
However, the defense did not perform at the level to which Buckeye fans are accustomed. The 2012 Buckeyes finished 34th in total defense, which was nearly 30 yards worse per game than the 2011 defense.
Making the improvement harder will be the loss of seven starters from last season, including all four defensive linemen.
So while the offense figures to pick up where it left off in leading the conference in scoring, the defense will need to reload and rebuild.
Ohio State's defensive success in 2013 will depend on building blocks—the steps this defense needs to take to become a championship-caliber defense.
