The BCS has resisted these pressures , and continues to argue that the BCS rating system is objective , fair , and superior to a playoff system . The BCS has been frequently maligned for excluding undefeated teams from national championship games ( University of Utah in 2004 and 2008 and Boise State University in 2006 ) while one-loss teams have competed for top honors . They have been further criticized for giving preferential treatment to teams in six specific " BCS conferences , " and for making special accommodations to include the University of Notre Dame as a " BCS school .
