The Ohio State football program is one of the most storied programs in all of college football. They have played a lot of games against a lot of programs across the country. In fact, they have played 91 teams that are currently in the FBS, the highest level of college football.
That still leaves a lot of teams that they haven’t played from other conferences. Ohio State tends to schedule fairly well, so they haven’t played a lot of smaller schools. But, there are some big-name schools out there that the Buckeyes haven’t played against either.
