It used to be that Ohio State players despised their longtime enemies to the North, Michigan, and abided everybody else.
Now the Buckeyes also have a special level of dislike for the Wisconsin Badgers.
Blame it on chippy, contentious games the past few years. Each side says the other's fans are obnoxious. Both have accused each other of grandstanding after victories.
Once just a blip on the schedule, now all of a sudden Wisconsin and Ohio State are bitter rivals.
"I don't want to go on record saying that I hate Wisconsin more than Michigan," Buckeyes wide receiver Corey Brown said, "but I hate Wisconsin just as much as Michigan."
A lot of that emotion will bubble to the surface when they meet again on Saturday.
