Dave Campbell: Kyler Murray leads Oklahoma past Texas in Big 12 championship game

ARLINGTON -- I found myself inside that huge AT&T Stadium (often called JerryWorld because that’s where Jerry Jones’ Dallas Cowboys play their home football games), but where this particular Saturday is where the Texas Longhorns and Oklahoma Sooners were getting ready to start the game that would decide which team will represent the Big 12 Conference as football champion and enter the so-called Final Four playoff to decide this season’s national champion. Other than Oklahoma, the other three teams will be defending champion Alabama, Clemson and Notre Dame. And that’s exclusive company.

But first Oklahoma had to defeat Texas, something they could not do back in October when they first played that Red River Showdown. The Longhorns won that thriller, 48-45. History (and the Las Vegas odds-makers) say it is extremely difficult for one good team to beat another good team twice in the same season. That’s why Oklahoma was favored by about 4 points in the early betting but by early Saturday the betting line had gone up to 7 points.
