 Called "The Battle of the Big Reds", the rivalry between the University of Oklahoma and Nebraska University was one of the most heated contests of the old Big Eight Conference.Played every Thanksgiving weekend for 71 years (from 1927 to 1998), this contest produced many memorable games; including the Game of the Century in 1971.The rivalry has cooled somewhat since the creation of the Big 12 as Bill Callahan's Nebraska Cornhuskers and Stoops's Oklahoma Sooners now split a home-and-home two of every four years.
