 The pre @-@ season editions of the Associated Press Poll and USA Today Coaches Poll pre @-@ season polls both ranked Texas number two in the nation behind defending National Champion University of Southern California . The two teams maintained those rankings throughout the entire 2005 regular season . Texas was ranked second in each week of the BCS rankings , except for one week where Texas took the top spot with USC falling to number two . The BCS rankings during 2005 were based on a formula which factored in the votes of two human polls ( the USA Today coach 's poll and the Harris Interactive poll ) , combined with a variety of computer rankings . The computer rankings favored Texas as the No. 1 team throughout the entire season , due partly to Texas 's wins over ranked programs such as Ohio State University and Texas Tech University .
