Here are some tidbits from around the conference that will shape how teams play their games this week.
1. Kansas: TB Angus Quigley, a third-stringer before the start of the season, has emerged as the team's most consistent rushing threat. Despite big expectations for Jake Sharp and Jocques Crawford before the season, it's been Quigley who's been the best runner. The Jayhawks need some kind of consistency rushing the ball for any kind of success against South Florida on Friday night.
2. Missouri: Coaches are hoping the return of S William Moore and LB Van Alexander will help boost their defense's production. The Tigers allowed 250 yards passing against Southeast Missouri State and surrendered 15- and 11-play drives in the first half of the game. That unit must improve before Big 12 play begins.
3. Iowa State: Look for the team to use Phillip Bates more against Iowa than in his first two games as he's backed up starting ISU QB Austen Arnaud. Bates' athleticism could give the Iowa defense some problems, particularly on option plays and other outside runs. Remember, Bates' 38-yard reception last season against the Hawkeyes was the key play in ISU's game-winning drive.
4. Oklahoma: Don't be surprised if top defensive recruit R.J. Washington gets his redshirt pulled this week. The Sooners' depth at defensive end is lagging as Frank Alexander recovers from a stab wound. And Washington has been routinely wowing coaches with his performance in practice. They believe it's about time for him to be tested in a game.
5. Oklahoma State: Despite Dez Bryant's huge game last week against Houston, look for Oklahoma State to try to develop other receiving threats this week against Missouri State. With Artrell Woods gimpy with a knee injury, players like Jeremy Broadway, Damian Davis, Josh Cooper and DeMarcus Conner need to produce to keep offenses from concentrating on Bryant.
