The Big 12 Power Rankings after Week 2:

1. TCU (previous ranking: 1): The Horned Frogs obliterated Stephen F. Austin 70-7 but lost another key defender in safety Kenny Iloka, who left with an apparent knee injury. TCU was already without linebackers Mike Freeze and Sammy Douglas, defensive end James McFarland and defensive tackle Davion Pierson. After a sluggish opener, quarterback Trevone Boykin and the offense looked great Saturday. But can the TCU defense survive this much attrition?

2. Baylor (2): Sure, the competition hasn't been good. Still, wide receiver Corey Coleman is putting up insane numbers. Through two games, he leads the nation with with 360 receiving yards and five receiving TDs. Only three other wide receivers in the Big 12 have more than 200 yards receiving. Oklahoma State's Justin Blackmon is the only receiver ever to win Big 12 Offensive Player of the Year; Coleman could seriously contend to be the second.

3. Oklahoma (4): Down 17-3 in the fourth quarter, the Sooners looked like they were done. They probably would've been last season. But displaying a renewed toughness spearheaded by quarterback Baker Mayfield, Oklahoma ground its way back to send the game to overtime, then won it 31-24 on Zack Sanchez's game-clinching interception. This is not the most talented team Bob Stoops has ever put together. But if the Tennessee performance was any indication, it could be one of the most hard-nosed ones -- and that would be most welcomed in Norman after recent seasons.

4. Oklahoma State (3): The Cowboys were underwhelming again in a 32-8 win over Central Arkansas, nowhere more so than in the running game. Lead back Chris Carson gained just 42 yards on 15 carries as Oklahoma State failed to establish the run again facing an inferior opponent. Despite strengths elsewhere, the Cowboys will have a hard time contending in the Big 12 unless the running game improves -- and fast.

5. West Virginia (5): There was no way West Virginia was going to seamlessly replace All-Americans Kevin White and Mario Alford, but Shelton Gibson and Jovon Durante are doing their level best. The two have touchdown grabs in each of West Virginia's first two games. Receiver might not be the strength it was last season for the Mountaineers, but behind Gibson and Durante, it doesn't appear to be a weakness, either.

6. Kansas State (6): In what could've been a tricky road trip to UTSA, the Wildcats took care of business in a methodical 30-3 win. Joe Hubener was solid in the first quarterback start of his football career, showing a strong arm in throwing for 243 yards, while also rumbling for 58 yards on the ground. He also didn't turn the ball over. The defense still hasn't given up a touchdown this season, either. It might not be flashy, and as coach Bill Snyder joked afterward, it might lull you to sleep. But K-State's winning formula for this season was on full display in San Antonio.

7. Texas (7): After Saturday, it's difficult to understand why quarterback Jerrod Heard hasn't been playing over Tyrone Swoopes all along. In Heard's first career start, the Texas offense finally came alive in a 42-28 win over Rice. Giving the Longhorns a much-needed jolt, Heard electrified with 120 yards passing, 96 yards rushing and two touchdowns through the air. Texas still has problems all over the field, but at least in Heard it has a quarterback who can produce big plays.

8. Texas Tech (8): Quarterback Patrick Mahomes has picked up where he left off last season, sitting second in the nation at the moment in passing. After two encouraging performances to start the season, Mahomes and the Red Raiders have an opportunity to show they're for real next weekend at Arkansas, which is coming off a stunning loss to Toledo.

9. Iowa State (9): The Cyclones had a chance to take a big step forward toward reaching bowl eligibility after jumping on Iowa early. Iowa State, however, gained just 66 yards after halftime, allowing the Hawkeyes to rally for the 31-17 win. Up next is a trip to Toledo, which is riding high after knocking off Arkansas. It's difficult to envision any scenario in which the Cyclones make a bowl going 1-2 in nonconference play.

10. Kansas (10): Only Tulane, Idaho and UTEP have given up more points through two weeks than the Jayhawks, who gave up 651 yards in a 55-23 loss to Memphis on Saturday. Kansas has an off week to regroup before traveling to Rutgers.
