327.5 miles.
That's the average distance from The Ohio State University to every other current member of the Big Ten athletic conference. If you get in your car at six in the morning, by lunchtime you will have been able to traverse the metaphysical distance between you, an Ohio State fan, and your understanding of every other school that the Buckeyes play.
This distance includes such far-flung places like Lincoln and Piscataway, of course; without the relatively recent additions of Rutgers, Nebraska, and Maryland, the average interval between Ohio State and every other Big Ten school is even closer, and this makes sense: when the Big Ten Conference was created in 1896 (Ohio State wouldn't join until 1912), the primary means of travel between the five states that comprised this athletic synod of Midwestern luminaries were giant steam locomotives capable of moving up to tens of miles per hour.
