Without question, the biggest feud in college football is between The Ohio State University Buckeyes and the Michigan Wolverines.
This historic rivalry dates all the way back to 1897 and over the years the Buckeyes and Wolverines have had some classic encounters.
The rivalry is over a century old, but the real feud began in the 1970s when Bo Schembechler took over Michigan after previously serving an assistant under Woody Hayes at Ohio State.
The hiring of Schembechler began what many people call the "Ten-Year War." Between 1969 and 1978 these two teams met 10 times and the hatred grew and grew.
Michigan went 5-4-1 over that span and Woody Hayes was fired in 1978 after punching a player in the Gator Bowl.
Hayes was not short on words about this rivalry and coined the phrase "the state up north," so he would not have to say the word "Michigan."
He became famous for his intense hatred of Michigan and legend has it that Hayes even refused to get gas with an empty tank in the state of Michigan.
Here is his reaction.
"No, goddammit! We do not pull in and fill up. And I'll tell you exactly why we don't. It's because I don't buy one goddam drop of gas in the state of Michigan! We'll coast and push this goddam car to the Ohio line before I give this state a nickel of my money!"
