I have seen a smattering of OSU stuff but to me is seems that Ohio gear outnumbers Ohio State gear at least 10:1. I saw far, far more Miami shirts yesterday than Ohio State.
I'll bet if you asked the average fan at an Ohio State game who the starting middle linebacker is 75% wouldn't have a clue. They just want to win. They know the quarterback, the running back, and a few receivers but don't understand the offense or know most of the lineman.
