DALLAS -- Texas-Oklahoma will be the most tempting game on today's Big 12 schedule, but it won't be the only treat.

The best game on the rest of the schedule will be when Texas Tech visits No. 15 Nebraska. Mike Leach has beaten the Cornhuskers the last three times he met. He'll have to wade through his quarterback controversy as he decides between Steven Sheffield or Taylor Potts as his starter against the Cornhuskers.

No. 16 Oklahoma State will try to continue its offensive success with backups as the Cowboys host Missouri. Dez Bryant remains out with an NCAA suspension and Kendall Hunter is hobbling with a knee injury. The Cowboys' backups picked it up last week against Texas A&M, but will be challenged against a Missouri team reeling after last week's fourth-quarter collapse against Nebraska.

Mark Mangino will try to cobble together a better defensive effort for No. 13 Kansas as the Jayhawks visit Colorado. Mangino promised changes after the defense struggled in recent victories over Southern Mississippi and Iowa State.

Something has to give when Baylor visits Iowa State tonight in Ames, Iowa. The Cyclones have an 11-game Big 12 losing streak and the Bears have lost 12 straight road games.

And Texas A&M will travel to Kansas State. The Wildcats' struggling defense allowed eight touchdown passes to Texas Tech last week and must do a better job against Texas A&M's Jerrod Johnson and Uzoma Nwachukwu this week if they want to win.
