Here are a few tidbits from around the Big 12 heading into this week's games.
1. The Big 12's most stable coaching staff might be set for a shakeup after the season. Missouri offensive coordinator Dave Christensen is in the mix for openings at New Mexico and Wyoming, and defensive coordinator Matt Eberflus is being considered for the vacant head job at Toledo. If either leave, they could become the first assistants from Gary Pinkel's staff to leave for another job. That stability has been an underrated facet in the Tigers' development into the North's strongest current program -- particularly in terms of recruiting two-star and three-star recruits in Texas who have blossomed into key contributors once they arrived in Columbia. A staff change would put Pinkel in the unfamiliar position of having to hire a new assistant for the first time since he arrived at Missouri in 2001.
2. Despite struggles in a disappointing 2-10 season, Iowa State coach Gene Chizik doesn't expect to go through heavy use of junior-college players to restock his program. Chizik said that "a couple" of junior-college players could be brought in to help the Cyclones at specific areas of need, but he doubted he would make a heavy push because those players would be around the program for only two seasons. Chizik still remains committed to using arriving high school talent as the backbone in his rebuilding job with the Cyclones.
3. Expect Oklahoma State to try to emphasize a more balanced approach in Saturday's game against Oklahoma than last season. The Cowboys have been working on play-action passing after throwing for only 104 yards last year against the Sooners -- the lowest in a Big 12 game in Mike Gundy's coaching tenure. The Cowboys hope to get tight end Brandon Pettigrew more involved Saturday after he was held without a catch last season by the Sooners. And the passing game should clearly benefit from the return of running back Kendall Hunter, who should be ready to go after nursing a quadriceps injury that occurred in the Cowboys' last game against Colorado.
4. Colorado's banged-up secondary will be at a big disadvantage Friday against Nebraska with senior starting strong safety D.J. Dykes out and starting free safety Ryan Walters' status still uncertain. It could mean a pair of freshmen will be starting against the high-powered Nebraska passing attack -- Anthony Perkins at strong safety and Patrick Mahnke at free safety. Nebraska quarterback Joe Ganz has to be salivating, considering he blistered the Buffaloes for 484 passing yards, 521 yards of total offense and four touchdown passes last season when the Buffaloes' secondary was a lot healthier.
5. Texas coaches have been disappointed in the last two seasons because their team wasn't as physical as A&M, losing the game in the trenches both seasons. It's led to a change in Texas' practices leading up to the Texas A&M game for the Longhorns. The Longhorns still should have the edge, considering that Texas A&M's offense isn't nearly as ground-oriented with Jerrod Johnson playing quarterback and with a young offensive line developing as it grows.
