No. 15 Kansas State (3-0, 0-0 Big 12) at No. 6 Oklahoma (2-0, 0-0 Big 12)

Kickoff: Saturday, 7:50 p.m. ET (FOX)

Spread: Oklahoma by 14

Watchability: This is the first must-watch game in the Big 12 this season and the Sooners' first chance to prove they're a legit title contender. The surprisingly big line could be because of last season's result -- a 58-17 Oklahoma win -- and the fact that Bob Stoops has owned Bill Snyder, winning seven of their eight meetings. Don't let that keep you from tuning in, as the Wildcats under Snyder are used to proving doubters wrong.

Shining stars: Oklahoma: QB Landry Jones. Jones nearly won this game by himself a year ago, throwing for 505 yards and five touchdowns. K-State's secondary is allowing opposing QBs to complete 67.3 percent of their passes (worst in the Big 12). The Sooners have leaned more on their running game thus far, but this could be the game to let Jones air it out. Kansas State: QB Collin Klein. Klein is completing 72.9 percent of his passes -- up from 57.3 percent last year. The Sooners will need to respect the K-State passing game, but they have to be more concerned when Klein is running the ball. He averaged 7.7 yards per run last week, and the Sooners rushing defense has not been overly impressive. They gave up 207 rushing yards and 5.8 yards per attempt in their opener at UTEP.

Who could steal the show: Oklahoma: RB Damien Williams. If the first 20 carries of his OU career are enough proof, Williams will be the surprise star in the Big 12 this year. He's averaging 12.9 yards per carry and leads the Big 12 with five rushing TDs. Kansas State: DE Adam Davis. Davis is tied for the Big 12 lead in sacks with three and leads the Big 12 with three forced fumbles. The Sooners, who have had injuries on the O-line, have given up a Big 12-worst six sacks after allowing only 11 last year.

You going? Ranking the road trip: The Sooners have three must-see home games this season: Kansas State, Notre Dame and Oklahoma State. This could end up being the best game of the three, considering K-State played nine games last season decided by a touchdown or less.

Magic number for Oklahoma: 100. As in 100 percent. The Sooners are perfect in the red zone this season, scoring 10 touchdowns on 10 trips.

Magic number for Kansas State: 89.3. That was the completion percentage of North Texas QB Derek Thompson, who entered the game with a 42 percent completion percentage but connected on 25 of 28 of his passes against K-State. If Jones has anywhere close to that kind of success, K-State could be in for a long day.

The game comes down to: The quarterbacks. Will OU's patched-together offensive line protect Jones enough to take advantage of K-State's secondary? Will Klein be able to perform against what looks like an improved Oklahoma defense with the return of Mike Stoops? The winner, if spectacular, will likely begin to get some Heisman buzz.

Prediction: Oklahoma 34, Kansas State 27
