I don't mind Herbstreit. He went against OSU during the Meyer controversy. Actually had to move out of Ohio to Kentucky due to constant harassment of his family for taking an anti-Urban stand. He has a son that is graduating from H.S. this year who chose to go to Michigan. KH went to OSU and so did his Father so he has strong ties to the school. He's personal friends with the Day family.
Having all that being said, I listened to his OSU broadcasts and, IMO, he's pretty much down the road. He gave ND all of the credit that they deserved during the game. The Irish were simply out manned by OSU. Willingham made some questionable decisions which happens when you don't have the horses to run in the race. Herbstreit called him on them.
