No. 1 – Texas Longhorns

The Sooners’ longtime rival from the Lone Star State is the only team from the Big 12 Conference that Oklahoma has a losing record against. And against opponents that the Sooners have played more than 11 times in their history, they have the worst winning percentage against the Longhorns.

The all-time series between these two Red River rivals is not only one of the longest running college series, it is also considered one of the greatest rivalries in college football history.

The Longhorns own a decided advantage in the series, posting a 44-61-5 record over their hated rival from north of the Red River. The series has been much closer, however, since the end of World War II. The post-WWII series record is 36-33-3 in favor of Texas.

Oklahoma has won 17 of the last 32 games, with two ending in ties, and since Bob Stoops has been the Sooners head coach, Oklahoma is 10-7 over the hated Longhorns.

In the 110 games between Oklahoma and Texas, there have been five ties and five have been decided by one point. The longest winning streak in the series was eight games by Texas between 1940 and 1947. The Sooners won six consecutive games in the 1950s under Bud Wilkinson (1952-57).

The highest scoring game was in 2008, when Texas defeated Heisman Trophy-winner Sam Bradford and the No. 1-ranked Sooners 45-35, and the widest margin of victory was in 2003, with Oklahoma hammering the Longhorns 65-13 behind another Heisman-winning quarterback, Jason White.
