On October 24, 2005, Texas passed USC in the BCS rankings due to a strong showing in the computer rankings, which favored the Longhorns because of the overall strength of their opponents as well as the October 22, 2005, win over previously unbeaten Texas Tech. The first-place ranking was the first for UT in the BCS era, and the first top ranking in any major football poll since October 8, 1984, when they were atop both the Associated Press and Coaches polls. The 0.0007% margin separating Texas from USC was the slimmest margin between the top two teams since the inception of BCS rankings.
