The Sooners are seven years removed from their shocking season-opening loss to TCU in Norman. OU was ranked in the top 10 and featured tailback Adrian Peterson. But TCU’s defense shut down Peterson and the Sooners and held on for the 17-10 win. The Horned Frogs lost only one game that season, while the Sooners would lose four more.

During Big 12 media days, Horned Frogs coach Gary Patterson was asked if he ever looks back at that landmark victory.

“Are you trying to make coach [Bob] Stoops mad at me?” Patterson said to the reporter. “You’ve got to learn from history, but the bottom line to it is you can’t look back too long.”

The loss didn’t dissuade Stoops from continuing to play the Horned Frogs. The two teams met again in Norman in 2008, with OU cruising 35-10. OU was scheduled to go to Fort Worth during the non-conference this season, then TCU jumped into the Big 12, making the meeting a conference game. The OU-TCU game on Dec. 1 will be the season finale for both schools and could have Big 12 title implications.

“They've been playing all of our teams through the years and they always play well,” Stoops said. “They're used to winning championships. Gary does an outstanding job coaching along with his staff. So they'll be tough. There's no question. I mean, they just went two years from winning the Rose Bowl and beating Wisconsin down there.

“They're a strong, good football team and program. So I'm sure it will be difficult. It will be a big challenge playing them.”
