It's more a conversation about rivalries, and their value to fans of CFB. I completely understand having little interest in a series of games against a team you lose to 90% of the time, but that occasional victory over them tastes better than for example, osu's last conference victory, which was over byu.
fan attendance shows us osu fans dont care nearly as much about playing byu, central florida, iowa state etc as when OU is in town, there must be a reason why attendance tends to be higher during bedlam.
