In 2004, the Longhorns began the season with a No. 7 ranking nationally and started out with a 65–0 blowout of , setting several UT school records in the process. This was followed by a narrow 22–20 win against unranked
Arkansas. They defeated
Rice and
Baylor 35–13 and 44–14 respectively. This left them ranked fifth coming into the annual matchup with then No. 2
Oklahoma in the
Red River Shootout. Oklahoma shut-out the Longhorns 12–0. Texas dropped to No. 9, before rebounding with wins over No. 24
Missouri 28–20, at No. 24 Texas Tech 51–21, and at
Colorado 31–7. Then Texas set a record for the largest come from-behind-win in school history, beating No. 19
Oklahoma State 56–35 after falling behind 7–35. After this performance, Texas again fell behind against
Kansas but squeaked out a win 27–23. Kansas coach Mark Mangino stirred up controversy by claiming that the officials were biased in favor of Texas. This brought UT back up to No. 5 in the rankings as they welcomed arch-rival
Texas A&M to Austin and won 26–13. However, Oklahoma stood undefeated, which meant the Sooners would represent the Big 12 South in the Championship game against a much lower ranked team from the North Division. Once again, the loss to Oklahoma had kept Texas out of playing for a National or Conference Title, and had seemingly destined them to a non-Bowl Championship Series bowl as well. However, Brown began lobbying the voters in the two polls based on human voters (one on
college football coaches, the other on
Associated Press (AP) writers) to place the Longhorns high enough in the rankings to ensure they received a
Bowl Championship Series (BCS) bowl-bid. The rules of the BCS were such that Texas might get left out of the eight chosen teams even though they ranked fifth nationally. The No. 4
California Golden Bears won their final regular season game 26–16 over 24-point underdog
Southern Miss. Cal did not try to run-up the score at the end of the game. Several AP voters were besieged by fan emails and phone calls attempting to sway their votes, apparently spurred from Brown's pleas to rank Texas ahead of other "less deserving teams." Nine of the 65 AP voters switched Texas ahead of Cal, and three of them were from Texas. In the coaches poll, four voters moved Cal down to No. 7 and two to No. 8, when the week before none had them lower than No. 6. Meanwhile, two coaches moved Texas up to No. 3 when the team did not play that week. The
Los Angeles Times wrote that accusations were raised about coaches manipulated voting, but the individual coaches' votes were not released to prove or disprove the allegations. The AP Poll makes its voters' records public. No. 6 Texas gained 23 points on No. 4 Cal in the AP poll, and the fifth-ranked Longhorns closed 43 points on the fourth-ranked Bears in the coaches poll. That allowed Texas to earn a BCS berth, finishing .0129 points ahead of Cal in the BCS standings after being .0013 points behind. Texas won the game 38–37 on a last second field goal kick by Longhorn
Dusty Mangum in what had been called one of the greatest Rose Bowl games of all time. It was the only time in the history of the Rose Bowl that the game has been decided as time expired off the clock. Vince Young set several Rose Bowl records and also won the Rose Bowl MVP award. ==After the season==
