STILLWATER — Perhaps the biggest victory in 123 years of Northwestern football came on opening day 1995. The Wildcats went to South Bend and upset Notre Dame 17-15. Northwestern, without a winning season in 24 years, went on to a glorious year. A 10-1 record, won the Big Ten and played Southern Cal in the Rose Bowl. But in Week 2, Northwestern lost at home to Miami-Ohio. In 2005, Texas Christian opened the season with a stunning upset of Oklahoma in Norman. Those Horned Frogs had a fabulous season: 11-1 record and No. 9 in the coaches’ poll. But in Week 2, TCU lost to SMU. Let those be lessons to the Oklahoma State Cowboys. A week of euphoria ends today when OSU hosts Houston. In the last seven days, OSU has dedicated a glittering stadium, knocked off Georgia 24-10 in one of the biggest games in Payne County history, rose to No. 5 in the AP poll and landed back on the Sports Illustrated cover. Not a bad week’s work. But it all goes for naught if OSU doesn’t take care of business today against Houston, no powerhouse but a far step up from SMU. "This is a trap game on paper,” admitted OSU offensive coordinator Gunner Brewer. The primary job of the Cowboy coaches this week was not strategic. It was psychological. Can they get their players to descend from the clouds? Mike Gundy on Monday still was talking about the revelry around town after the momentous weekend, and then came the AP/SI flurry mid-week. But "you’ve got to let it go,” Gundy said. The staff had a plan for just that. Show the defense tapes of the 2008 Houston game, in which the Cougars led at halftime before falling 56-37. Show the offense tapes of last week, when the 24 points against Georgia came without ease and with help from turnovers. "The jury’s still out on how good we are,” said d-coordinator Bill Young. "The jury’s still out on how good Georgia is on offense. We’re not going to let this go to our head.” Easier said than done. The Cowboys have been riding high and walking tall all week, and who can blame them? These are heady days in Stillwater, and a post-Georgia letdown would only be natural. "We haven’t arrived yet,” Brewer said he told his troops. "Offense is not up to the level they expect. If you want to be a champion, start carrying yourself like one.” But maybe positive reinforcement is the better method. Gundy said his motivational tactics wouldn’t center on where the Cowboys have failed, but the opportunity that presents itself. "You only get to play 14 of ’em a year,” he said of games, and take note of that number. OSU will play 14 games only if they win the Big 12 South and thus reach the championship game. Gundy is talking in positive terms. "These guys train about 340 days a year to play 14 times. You can’t get it back.” Just ask Northwestern and TCU.
