What is the name of the tournament that was formed by the Big 12 Conference that led to the Nebraska-Texas rivalry?
Nebraska–Texas football rivalry The Nebraska–Texas football rivalry was an American college football rivalry between the Nebraska Cornhuskers and Texas Longhorns. The rivalry dissolved when Nebraska left the Big 12 Conference for the Big Ten Conference. Due to Colorado, Missouri, Nebraska, and Texas A&M leaving the conference, the Big 12 Championship Game dissolved due to a lack of teams in the conference. The last ever Big 12 Championship game was played between Nebraska and Oklahoma in 2010.
Sitting Bull Trophy The Sitting Bull Trophy is the name of the rivalry trophy that was awarded to the winner of the annual football game between the University of North Dakota Fighting Hawks (formerly the North Dakota Fighting Sioux) and the University of South Dakota Coyotes. The rivalry stems from the time the two teams spent competing together in the North Central Conference (1922–2007) and later in the Great West Conference (2008–2011).
