The Ohio State Buckeyes are ranked No. 1 in the nation, unbeaten halfway through the regular season, and the favorites to win another national championship. But there are still concerns about areas where the team needs to improve. 

One is the run game, where the Buckeyes ran for less than three yards per carry in a win over Illinois. So what's holding the OSU rushing attack back? Is is offensive line play? The lack of an elite back? Or is the coaching staff just not taking advantage of easy opportunities to work on areas where they need to improve?

Ross Fulton, the Xs and Os guru at BuckeyeHuddle.com joins host Tom Orr to discuss that and much more.
