The Ohio State football program has been the top-ranked team in the country since taking down Texas in the opener. Since that first game, they have won every game by at least 18 points. In terms of their defense, the Buckeyes have the best scoring defense and the best in terms of yards allowed.
Ohio State is the defending national champion, and they're playing like it. There's a good chance that the Ohio State Buckeyes are better than last year's team because of their ability to smother opponents with their defense. Offensively, they are finally starting to hit their stride.
