Here are a few items to watch for around the Big 12 this week
1. Expect a more balanced Colorado offensive attack against West Virginia with the return of TE Riar Geer, who missed the last two games with a sprained knee. His return will give the Buffaloes an intermediate receiving threat important against West Virginia's 3-3-5 defense. Don't be surprised if it also boosts the confidence of QB Cody Hawkins, who will have his favorite target from last season returning.
2. Despite being overshadowed by linebacking mates Joe Mortensen and Mike Rivera, Kansas LB James Holt is being used as the team's top blitzer in new coordinator Clint Bowen's schemes. Holt responded with a game-high 13 tackles, a sack and forced two fumbles while thriving in his new role against South Florida.
3. Junior-college transfer RB Keithen Valentine will get the majority of playing time against Louisville and not just because of his rushing abilities. Kansas State coaches think the 5-foot-8, 197-pound Valentine is the best antidote they have for Louisville's blitz tendencies.
4. Don't be surprised if Missouri opts to bench S William Moore for this week's game against Buffalo. Moore, the Tigers' inspirational leader and best defensive back, tweaked his injured ankle against Nevada. The Tigers would like to have him as near to 100 percent as possible for the start of conference play Oct. 4 at Nebraska.
5. Iowa State QB Austen Arnaud got all the snaps except for three series against Iowa. Despite that imbalance, Iowa State coach Gene Chizik remains committed to a two-quarterback system where Phillip Bates will see some playing time in every game. Chizik likes to use his quarterbacks depending on feel. He expects to use both this week against UNLV.
