1. No. 1 Oklahoma (2-0) (–) — The Sooners cleared a major hurdle in beating Florida State. The door is now wide open for a national championship berth. It’s theirs for the taking.

2. No. 7 Oklahoma State (3-0) (+2) — The Cowboys have come out of nonconference play unscathed, but now have a tough top-10 game ahead of them in possibly their last-ever matchup against Texas A&M.

3. No. 8 Texas A&M (2-0) (-1) — The Aggies continue their farewell tour of the Big 12 with a game against No. 8 Oklahoma State. A convincing win would leapfrog the Aggies over the Cowboys in the polls.

4. No. 17 Baylor (2-0) (-1) — In two games, quarterback Robert Griffin III is 41-of-46 in pass completions for 597 passing yards and eight touchdowns.

5. No. 19 Texas (3-0) (+1) — Case McCoy has become the savior at quarterback for the Longhorns, who pounded UCLA on Saturday and will be well-rested heading into Big 12 play against Iowa State on Oct. 1.

6. Iowa State (3-0) (+2) — Winning sloppy is still winning. The Cyclones have one of the toughest schedules in the nation from here on out, so a bye week comes at a great time.

7. Missouri (2-1) (-2)  — Ravaged by injuries, Missouri will need some help if it wants to beat No. 1 Oklahoma on the road.

8. Texas Tech (2-0) (-1) — A weak nonconference schedule has knocked the Red Raiders down a peg in the Big 12 power rankings.

9. Kansas State (2-0) (+1) — A roadtrip to Miami awaits Bill Snyder and Co., which has allowed a nation-best 3.5 points per game in its first two contests.

10. Kansas (2-1) (-1) — Cloud nine proved too lofty for the Jayhawks, who enter Big 12 play allowing 33 points per game, which is 96th in the nation.
