Here’s what we learned about the Big 12 in Week 7:

1. No matter how far down, Baylor is never out: TCU led the Bears by three touchdowns with just over 11 minutes left in the fourth quarter. After a pick-six, the Horned Frogs had all the momentum, too. Yet even all that wasn’t too big an obstacle for Art Briles’ club to overcome. Behind quarterback Bryce Petty, the Bears put together touchdown drives of 45, 92 and 91 yards covering a combined 3 minutes, 21 seconds to tie the game. Then after stopping TCU on fourth down, Shock Linwood (who had 104 yards rushing in the fourth quarter) bulled the Bears into field goal range to set up Chris Callahan’s 28-yard game winner, which lifted the Bears to the improbable 61-58 win. Baylor never lost its resolve, even after Marcus Mallet’s pick-six of Petty that put the Bears in a seemingly insurmountable hole. That speaks to the character of the team and of the program. And it bodes well for Baylor’s Big 12 title and playoff hopes the rest of the season.

2. Bryce Petty is officially in the Heisman race: After a banner junior season, Petty started out the year on the short list of Heisman contenders just below reigning Heisman winner Jameis Winston. But the combination of a back injury and a soft early-season schedule knocked Petty off the radar. On Saturday, Petty returned to the Heisman picture with authority, delivering his Heisman moment -- or moments -- while rallying the Bears in the fourth quarter against TCU. Petty threw for a career-high 510 yards and six touchdowns, including two in the fourth quarter. With Winston struggling and Georgia running back Todd Gurley ineligible indefinitely, the Heisman race is wide open. As long as the Bears keep winning, Petty could surge to the top of the Heisman conversation.

3. TCU still has a really good team: The Horned Frogs played phenomenally in Waco, Texas, for 50 minutes. Unfortunately for them, they had another 10 minutes still to play. This epic collapse won’t be easy to put in the rear-view mirror. The Horned Frogs had a prime opportunity to beat a top-5 team for the second straight week while putting themselves in the driver’s seat of the Big 12 title and a playoff spot. But TCU couldn't make any plays in the final 10 minutes of the fourth quarter, including a crucial failed fourth-and-3 attempt on a questionable fade call that set up Baylor's game-winning field goal. Nevertheless, this remains a very good TCU team that could still be a major player in the Big 12 title race. Which means, despite Saturday's fourth-quarter collapse, this season could be a special one for a team that is vastly improved from its first two years in the league.

4. Texas has reason for hope: The Longhorns might have lost the Red River Showdown 31-26, but they also showed there’s hope for this season and hope for this program under Charlie Strong. Texas completely dominated the box score, outperforming the Sooners in almost every statistical category. Oklahoma's big plays ultimately did Texas in. But even when the Sooners led 31-13 in the fourth quarter, the Longhorns didn’t give up. Quarterback Tyrone Swoopes threw for a career-high 334 yards and displayed tremendous poise in a building-block performance. The Texas defense was also dominant again, and is looking more and more like it might be the class of the league. With a 2-4 record, the Longhorns have an uphill climb to make a bowl game. But Strong had to feel better about his club leaving Dallas than he did arriving.

5. West Virginia, Oklahoma possess gumption: The Baylor comeback overshadowed another amazing display of resiliency in the Big 12, as the Mountaineers rallied from a late 14-point deficit to stun Texas Tech 37-34 earlier in the day. The Mountaineers scored 17 points in the final six minutes of the fourth quarter, which ended on Josh Lambert’s game-winning field goal from 55 yards out (Lambert also had the game winner that beat Maryland). The Mountaineers struggled all day offensively in Lubbock, Texas, but they turned it on when they had to. Speaking of a struggle, Oklahoma's win over Texas didn't come easy. The Sooners had just one first down the entire first half, then nearly squandered a 31-13 lead in the fourth quarter. Yet from Alex Ross’ kickoff return touchdown on the Sooners’ first touch of the game to Samaje Perine’s two third-down conversions on their final drive, the Sooners made the plays they had to make to win. Even when not at their best, good teams find a way to win. That's what the Mountaineers and Sooners did Saturday.
