Four-star viewers' guide for this week's Big 12 games

Posted by ESPN.com's Tim Griffin

The Big 12 crashed the national polls on Sunday with more teams ranked in the top 10 than any other conference.

And even with conference play beginning, those rankings should hold if the ranked teams all can win on Saturday. The first week of Big 12 play features no games between two ranked foes.

But it should provide a couch potato's dream with five game available from late morning until nearly midnight.

Here's a viewer's guide to help guide you through your afternoon. Plan your Saturdays and set your Tivos accordingly.

Like always, a ranking of four stars indicates must-see television, and maybe even a game tape to be savored by more devoted viewers. Three-star games are worth the investment in time. Two-star games bear a quick glimpse or two for occasional score updates. And one-star games are indications that your time might be better spent with your family away from the television.

All kickoff times are for those viewers in the Eastern time zone.

Four-star game

Texas Tech at Kansas State, 3:30 p.m., ABC-TV: Will the Wildcats' leaky defense show much improvement after two recent struggling performances? Mike Leach and the Red Raiders are licking their chops thinking about their opportunities.

Three-star game

Texas at Colorado, 7 pm. Fox Sports Net: Buffaloes hook up with Longhorns for the first time since their historic 70-3 blowout victory in the 2005 Big 12 championship game. Throw in the bad feelings from Darrell Scott recruiting battle between the two schools and you could have a grudge battle.

Missouri at Nebraska, 9 p.m., ESPN: Wounded Cornhuskers still have history on their side. Missouri last won in Lincoln in 1978 and it will facing a difficult task Saturday night. But I bet that Bo Pelini will remain rather silent along the bench after last week.

Two-star games

Oklahoma at Baylor, 12:30 p.m., Fox Sports Net: No. 1 Sooners should have a chance to build confidence in their running game with Red River rivalry looming. But their defense will be challenged by talented Baylor freshman QB Robert Griffin, who will be facing his biggest college test so far. The Sooners have never lost to Baylor in the 16-game series.

Kansas at Iowa State, 12:30 p.m., Versus: Jayhawks hope to start their North Division title hopes by claiming their first road game of the season. Something will have to give in the pillow fight between Kansas' impotent rushing game (94th in the nation) against Iowa State's struggling rush defense (95th nationally).

Texas A&M at Oklahoma State, 7:05 p.m.: The Aggies have dominated this series in recent years, claiming 10 of the last 12 games including a pair of one-point victories in the last two seasons. But that was then and this is now. This one could get ugly as the Cowboys' No.1 ranked rushing game will face an A&M defense that ranks 115th nationally against the run and 76th overall in total defense.
