 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 cooled somewhat since the creation of the Big 12 as Bill Callahan's Nebraska Cornhuskers and Stoops's Oklahoma Sooners were split a home-and-home two of every four years.This was only the fourth time that the teams had met at a neutral site.
