My favorite excerpt:
So the story goes ... Hayes took his team to play Illinois in 1970. During the trip he asked them: "What would you be doing in Columbus on a Friday before game day?" Several Buckeyes answered they'd be in class. Woody agreed, so he instructed all of his players to split up and attend a lecture on Champaign's campus that Friday. Hayes took stars Jim Stillwagon and Rex Kern with him. They didn't know what type of class it was until they sat down at the front of the class. Hayes apologized to the chemistry professor for the disturbance then started taking notes. Midway into the lecture, the professor offered his theorem on the board. Hayes raised his hand and soon the professor called on him. "Sorry to bother you, but I think your theorem is off a little, professor." Stunned, the professor stood back and took another look at his work on the board. He then grabbed an eraser, removed a numeral from the theorem and replied, "Thank you, coach Hayes."
