It's no surprise that much of Ohio State's recent success can be tracked to a powerful, and consistent, running game. The Buckeyes have had talented running backs and a big, aggressive offensive line that has opened huge holes for those backs to run through. An often underrated part of the ground game, especially for the Buckeyes, is the importance of solid perimeter blocking and the Ohio State's recent wide receivers, guys like Evan Spencer, Devin Smith, Mike Thomas, Jalin Marshall and others, are well above average in that part of their game.
Of course, they've also begun to make quite an impact in the passing game as well.
