Here's what I saw on a Saturday full of surprises across the Big 12 in Week 9:

Best offensive performance: Steele Jantz, QB, Iowa State. Cry about Baylor's defense all you want, but Jantz had to complete the passes. He had a huge career day, completing 36 of 53 passes for 381 yards and five touchdowns with an interception in ISU's 35-21 win over Baylor. He also ran for 54 yards on 10 carries.

Best defensive performance: Elisha Olabode, S, TCU. The Frogs safety had a huge day with 10 tackles and a forced fumble. His biggest play, though, was an 11-yard interception return for a touchdown that put TCU up 7-0 early.

Best team performance: Kansas State. Another top-15 team, another dominant performance from the Wildcats, who rode a huge second-half surge to a head-turning 55-24 win over Texas Tech. K-State made it look easy in the second half.

Best game: Texas 21, Kansas 17. This one was unwatchable for the first three-and-a-half quarters, but you've got to love some late drama. No other Big 12 game this week had it. KU kicked a go-ahead field goal with 2:28 to play, but Case McCoy entered in relief and rallied the Longhorns to a dramatic comeback, highlighted by a fourth-down conversion to Jaxon Shipley. More on that later.

Best quote: Tony Jefferson, S, Oklahoma. "I hate this. I hate this feeling." Sometimes, a few words says all you need to know. Simple, but poignant from the Sooners' star after a frustrating 30-13 loss to Notre Dame at home.

Worst play: Kansas State's latest red zone disaster. Facing a third-and-goal and the game tied at 10, Kansas State handed the ball off to Angelo Pease, who stopped short of the line of scrimmage and attempted a jump pass. The only problem? He was hit as he threw it, and it was some sort of weird two-handed, overhead toss that fell incomplete. Ugly stuff, and this is the second time this year K-State has earned this nod for a play in the red zone. Earlier this year, Collin Klein attempted a behind-the-back jump pass for a huge loss. At least K-State made the field goal this time. It missed it after the disaster against Miami.

Dirtiest play: Cyril Richardson, OL, Baylor. There are plenty of ways to get a player off you. Kicking them in the groin should be nowhere on that list. Richardson kicked upward and connected with the groin of Iowa State's Brandon Jensen, earning himself an ejection and helping prevent the Bears from scoring on the early fourth-quarter drive.

Best play: Case McCoy x 2. The first ignited a game-winning drive that hardly even started. McCoy found Shipley over the middle for an 18-yard gain to keep the Horns alive. Later in the drive, he found Mike Davis over the top for a 39-yard gain to set up Joe Bergeron's game-winning touchdown in the Horns' 21-17 win over Kansas.

Best special-teams performance: Quinn Sharp, P/K, Oklahoma State. Sharp made five field goals and pinned TCU inside its 20-yard line on two of his five punts. Nice day.

Worst team performance: Texas. Even with the win, I can't let the Horns off the hook here. Kansas has lost 17 consecutive Big 12 games now, but outplayed the Horns and held them to just seven points over the first 3 1/2 quarters on Saturday. Texas had 60 more penalty yards and needed a dramatic rally, despite winning the turnover battle 3-1. It also made an inexplicable switch to McCoy after David Ash struggled early. Once McCoy was in the game, Texas ran seven consecutive running plays on a touchdown drive, and now may have a quarterback controversy on its hands. That said, it should just play Ash.
