One game, 60 minutes, four quarters are all that separate Ohio State from a season for the ages.
Just five teams in the program's 122 previous years have gone through a campaign unbeaten and untied. The Buckeyes (11-0, 7-0 Big Ten) can become the sixth on Saturday when they take on their rival Michigan.
Since the two officially saved the best for last and moved their biggest game to the end of the schedule in 1935, Ohio State has carried a perfect record into the Michigan game 12 times, going 8-3-1.
Is there added pressure defending a spotless season? Is there added incentive for your chief adversary to ruin one?
These and more questions will be answered in the 109th meeting at a packed Ohio Stadium.
