Here are our Big 12 power rankings after Week 1:

1. TCU (previous ranking: 1): QB Trevone Boykin will surely have better days than he did in a sluggish 23-17 victory at Minnesota, but the Horned Frogs need to heal up before Big 12 play kicks off later this month. With Stephen F. Austin and SMU coming up, they have plenty of time to do that before traveling to Texas Tech on Sept. 26.

2. Baylor (2): The Baylor defense was anything but impressive in the opener against SMU, but getting All-Big 12 DE Shawn Oakman and S Orion Stewart back from one-game suspensions should help settle the unit down. That said, this Baylor offense could be absurd. Corey Coleman and KD Cannon form what appears to be the best WR tandem in college football, and with Jay Lee, who caught three TDs in the opener, the Bears seem almost unstoppable at receiver.

3. Oklahoma State (3): The Cowboys had to grind their way to a midweek win against Central Michigan. Oklahoma State wasn't sharp, but QB Mason Rudolph was in his fourth career start, completing 22 of 32 passes for 266 yards in the rain. Rudolph also flashed some mobility with a 21-yard TD run. The Cowboys will have to tackle better, and the offensive line will have to pave more holes for the running game. But as long as Rudolph continues to perform, Oklahoma State figures to be a load.

4. Oklahoma (4): The running game was shaky early in a 41-3 win against Akron, but the passing game behind QB Baker Mayfield, coordinator Lincoln Riley and newcomers Dede Westbrook and Joe Mixon looks recharged. The first real test, however, comes Saturday at Tennessee, a game that should reveal whether Oklahoma could be a factor in Big 12 title and playoff conversations. Establishing Samaje Perine and the running game early will help.

5. West Virginia (5): West Virginia's veteran defense was dominant in a 44-0 stomping of Georgia Southern, suggesting this Mountaineers defense could be for real. Georgia Southern coach Willie Fritz would agree, calling the West Virginia defensive backfield "the best secondary I've ever witnessed up close personally." The 100-yard receiving performances of Shelton Gibson and freshman Jovon Durante were encouraging, too.

6. Kansas State (7): K-State moves up a spot mostly because of the Longhorns' struggles, but the Wildcats have some concerns of their own after Week 1. Coach Bill Snyder said starting QB Jesse Ertz would "be out for quite some time" with a knee injury, suggesting his season is done. K-State will turn to Joe Hubener, and possibly freshman Alex Delton, who won't be redshirting now. Standout defensive backs Danzel McDaniel and Dante Barnett were injured in the opener, too. The Wildcats have a tricky road trip Saturday to UTSA, which gave Arizona a scare in the opener.

7. Texas (6): One week in, and already the Longhorns are a mess yet again. After his offense failed to score a TD in the season-opening loss at Notre Dame, coach Charlie Strong didn't exactly give offensive coordinator Shawn Watson a vote of confidence at Monday's news conference. Watson could help his cause by giving Jerrod Heard more of a look at QB this weekend, but QB is hardly Texas' only problem. The offensive line looked terrible in South Bend, and the defense wasn't impressive except for star freshman LB Malik Jefferson. With Oklahoma State, TCU and OU looming, Texas needs to right the ship quickly, or this could be a long season in Austin.

8. Texas Tech ( 8): QB Patrick Mahomes was electric in Tech's win against Sam Houston State, but defense remains a huge question after Tech surrendered 45 points. Getting the reigning Big 12 sack champ Pete Robertson back from suspension would help, but first-year coordinator David Gibbs still has his work cut out. One sign of growth is that Tech won the turnover battle 4-to-1 in the opener. Ball security and forcing turnovers will be paramount for a team that was minus-13 in turnover margin last season.

9. Iowa State (9): After disastrous openers in back-to-back seasons, the Cyclones had to be pleased with their sharp 31-7 win against Northern Iowa, which toppled Iowa State in Ames two years ago. A win against the Iowa Hawkeyes this weekend would be a huge step toward reaching bowl eligibility and would give the Cyclones a ton of momentum heading toward Big 12 play.

10. Kansas (10): The Jayhawks dropped their opener to South Dakota State in heartbreaking fashion, as QB Montell Cozart fumbled the snap while trying to spike it to set up a potential game-tying field goal. With the loss, Kansas could be staring at an 0-12 record in coach David Beaty's first season. The Jayhawks will be heavy underdogs the rest of the way, including this weekend against Memphis, which is favored to win by two touchdowns.
