Best matchup: This weekend's clash matching No. 19 Oklahoma and No. 23 Missouri in Columbia, Mo., is the only game in the nation featuring two ranks teams. Missouri quarterback Chase Daniel, who has thrown 19 touchdown passes and only five interceptions, directs an offense which ranks 14th nationally. Meanwhile, the Oklahoma defense has improved to No. 11 nationally after allowing nine or fewer points in three of their last four games.
Worst matchup: Iowa State and Kansas State have combined for one victory in conference play, and the Wildcats needed a furious rally to top Oklahoma State three weeks ago. Kansas State enters this game having lost four of its last five. Iowa State is on a three-game losing streak since escaping with a 28-27 victory over Division I-AA Northern Iowa.
The pressure is on: Kansas and Iowa State are both 3-5. With only four games remaining, they still need three more victories to earn bowl eligibility. If either loses this week, they will be facing postseason elimination the rest of the season. By the way, the Jayhawks play the Cyclones in Ames, Iowa on Nov. 4.
Upset alert: If Nebraska is experiencing any hangovers from its 22-20 heartbreaking loss to Texas last week, the Cornhuskers could be in trouble. Pass defense isn't exactly the Huskers' forte, and the Cowboys have managed 10 touchdown passes in their last three games.
Who's hot: Baylor quarterback Shawn Bell passed for a school record 394 yards and five touchdowns – three in the fourth quarter – in a 36-35 come-from-behind victory over Kansas last week. In the last four games he has thrown for 1,251 yards and 11 touchdowns. The Bears have gone 3-1 in that stretch.
Who's not: The Kansas defense – linemen, linebackers, safeties, cornerbacks, nickel backs and anyone who coaches that unit. The Jayhawks have squandered double-digit leads in the second half of their last three games and have been outscored 54-15 in the fourth quarter in that span. The last two quarterbacks they've faced – Oklahoma State's Bobby Reid and Baylor's Shawn Bell – both set school records (Reid for total yardage, Bell for passing yardage) and combined for 10 touchdown passes.
BCS implications: Texas, which this week goes to Texas Tech and has a history of struggling in Lubbock, is No. 7 in the BCS standings. No other Big 12 team is higher than 19th (Oklahoma), so at this point only games involving the Longhorns have significant meaning to the BCS race.
Most to lose or gain: The hot seat Texas A&M coach Dennis Franchione was on at the beginning of the season has turned into a throne – or at least an easy chair – because the Aggies are 7-1. He's getting praised again in College Station and the Aggies are in control of their destiny in the Big 12 championship race. However, all that will change on Saturday if the Aggies fall to Baylor. As a collective group, the Aggies don't want to acknowledge that the Bears have reached competitive balance with A&M under coach Guy Morriss. Last year the Aggies needed overtime to subdue the Bears. Two years ago they were beaten in overtime in Waco.
Must see TV: The best matchup is Oklahoma-Missouri, while Oklahoma State-Nebraska might be most conducive to an upset. But if you can only watch one Big 12 game this weekend, tune into Texas vs. Texas Tech on TBS. The No. 5 Longhorns have won 19 consecutive conference games, and haven't lost a Big 12 game on the road since losing 42-38 against Tech in Lubbock in 2002. Crazy things often happen when Tech hosts Texas in a night game, and that could be the case again. Tech quarterback Graham Harrell has thrown for 2,505 yards – the nation's third highest total – and every starter in the Texas secondary is nursing some kind of injury.
Newcomer/backup that could have an impact: True freshman offensive tackle Trent Williams moves into Oklahoma's starting lineup after starter Branndon Braxton suffered a season-ending fractured tibia in last week's win over Colorado. OU praised Williams' play in that game, and he'll need to continue performing at a high level this week against Missouri. The Tigers rank eighth nationally in sacks. However, Brian Smith, the Tigers' leading pass rusher with 7½ sacks, suffered a fractured hip in last Saturday's victory over Kansas State and will miss the remainder of the regular season.
Key stat: Missouri has not beaten Oklahoma and Nebraska in the same season since 1969. The Tigers (7-1) face Oklahoma on Saturday and Nebraska next week.
Take the line: Oklahoma State has allowed at least 31 points in its last four games. That's reason enough to give up 5½ points and take Nebraska - even though the game is in Stillwater, Okla. Zac Taylor is a solid quarterback and the Cornhuskers get excellent production at running back. Now, if they can figure a way to get Maurice Purify the football more than two or three times a game they could score in the 30s, too. Oklahoma State's offense can be explosive, and the Huskers may still be in a state of shock after losing to Texas. However, they still should be able to top the Cowboys by a touchdown. Season record: 3-5
