A change in the top has been reported after Oklahoma's second-straight impressive victory to start the season:
1. Oklahoma -- Surging Sooners hope for better luck -- and better officiating -- at Washington than they received on their last trip to the Pacific Northwest.
2. Missouri -- No problems with the Tigers, even though the decision to play Jeremy Maclin against SE Missouri State looks a little more dubious with the final margin of victory.
3. Texas -- A bow to the past this week as Arkansas visits. Only trouble is that Bobby Petrino is anything but the normal Razorback coach that Texas fans have loathed over the years.
4. Texas Tech -- Defense saves the Red Raiders from crapping out in Nevada, despite a career-worst start for Graham Harrell, in terms of completions.
5. Kansas -- Remember when Jocques Crawford talked about rushing for 2,000 yards? The lack of a productive running game is the Jayhawks' biggest concern heading into the South Florida showdown.
7. Kansas State -- Maybe Josh Freeman wasn't bragging. He is playing like the best of the Big 12's quarterbacks, even though he hasn't played against a competent defense yet.
8. Nebraska -- The Cornhuskers' defensive woes get more serious with the loss of top pass-rusher Barry Turner for the season. And it's coming at a bad time as pass-happy New Mexico State approaches.
9. Colorado -- The Buffaloes have work to do as they prepare for West Virginia's visit. CU's defense improved in the second half, but was still lucky to escape with victory over plucky Eastern Washington.
10. Iowa State -- The Cy-Hawk Trophy has looked good in the Cyclones' athletic offices the last few years. Gene Chizik would like nothing more than claim his second-straight win over Iowa.
11. Texas A&M -- Hold off on a potential quarterback controversy because of their week off. But Jerrod Johnson's improvisational skills might be better suited for working with A&M's young line.
12. Baylor -- Beating up on Northwestern State felt good for the Bears. It also represented Robert Griffin's impressive coming-out party as a starting college quarterback.
