No kidding. Woody Hayes was never in a playoff. He coached in an era where the national championship was determined by a beauty contest. At that time, it would be impossible for Ohio State to win the beauty contest without beating Michigan. There were years where Woody went undefeated but wasn't even allowed to go to a bowl game.
Ain't gonna win the 'ship losing the last game of the season.
I firmly believe there will come a day (not in my lifetime, it may take another 75 years like the last time) but Michigan will lose to Ohio State, make the playoffs, and win the tournament. If that dark day ever comes, they will be the champions.
