I am of the camp that only michigan is a rival. However, perhaps we need to re-think this.
Penn State gets extremely fired up every time they play The Buckeyes.
Always a night game "white out".
Their fans come out ready to help the team and create a super hostile environment.
Ohio State needs to start looking at this game with a little more importance because PSU is going to get more scholllies and only get better. If we don't look at this game in the same manner it could bite us.
