There are rivalries. And then there are rivalries.
Ohio State doesn't like Michigan. The Wolverines don't like the Buckeyes.
If you plan to visit the Woody Hayes Athletic Center in Columbus, you better make sure to check your wardrobe before getting to the door.

Recently, when NFL scouts were first allowed to view a Buckeyes practice, at least two of them were wearing blue.
So what you ask?
That's a no-no.
According to a FoxSportsOhio.com report, some players yelled at the scouts about wearing blue and the scouts eventually were given Ohio State shirts to wear instead of their blue shirts.
"It's just not something that needed to happen," one scout, who was not there that day, told FoxSportsOhio.com. "It could have been handled much better, and if that (blue-shirt) rule is going to be enforced, they could let us know."
Now everyone knows.
And Ohio State plays at Michigan this season.
