Big 12 weekend rewind: Week 2

Time to look back on the week that was in the Big 12 on Saturday.

Best offensive performance: Collin Klein, QB, Kansas State. Klein dominated in the Wildcats' 52-13 win over Miami, showcasing an improved arm and the same toughness that made him a franchise player for K-State a year ago. He finished with three rushing touchdowns and 71 yards on 22 carries, while completing 9 of 11 passes for 201 yards, a touchdown and an interception. Honorable mention: Tracy Moore, WR, Oklahoma State, Damien Williams, RB, Oklahoma

Best defensive performance: Adam Davis, DE, Kansas State. Davis was a wrecking ball on the defensive line for K-State, the game's most consistently disruptive force. He finished with just four tackles, but he had two sacks and forced two fumbles, one of which was scooped up by Arthur Brown. Honorable mention: Arthur Brown, LB, Kansas State

Best performance by a freshman: Devonte Fields, DE, TCU. The Horned Frogs' hyped defensive end was all over the place against Grambling, making five tackles, a sack and three tackles for loss for a total of 10 yards lost. Heck of a debut for the most touted member of TCU's 2012 recruiting class.

Best play: Jake Knott, LB, Iowa State. Knott clinched the Cy-Hawk Trophy for Iowa State by tipping a James Vandenberg pass to himself for a game-ending interception, cutting off a promising Iowa drive in the final minute of the Cyclones' 9-6 win over the Hawkeyes. Honorable mention: Cody Davis, S, Texas Tech; Kenny Williams, RB, Texas Tech

Worst play: Kansas State's ... something. It was half jump pass, half behind the back Statue of Liberty ... or something. Bill Snyder called a timeout and the Wildcats ran the trick play at the goal line. However, Klein's behind the back pass to Chris Harper ended up going for a 19-yard loss and the Wildcats missed a field goal on the next play.

Second-worst play: Calvin Barnett, DT, Oklahoma State. It's been a long time since I've heard of a player getting two personal fouls on the same play, but Barnett pulled it off in the first quarter, getting flagged for two personal fouls to take care of 30 yards for Arizona on a 75-yard touchdown drive. He was flagged for roughing the passer and again for unnecessary roughness, and finished with 45 penalty yards, 18 more than Arizona's entire team. Oklahoma State finished with a school-record 167 penalty yards on 15 flags. Dishonorable mention: Dayne Crist's fourth-quarter interception to set up Rice's game-winning field goal.

Best team performance: Kansas State. We saw a complete game for 60 minutes and complete domination from the Wildcats. K-State sent a pretty decent statement with one of the best all-around games we've seen all season from anybody in the league, routing Miami 52-13, and outmuscling a pretty athletic Hurricanes squad.

Worst team performance: Oklahoma State. The Jayhawks gave OSU a run for its money in this one, but when you add up the aforementioned penalties, four turnovers and zero forced turnovers and the fact they came against a middling Arizona squad, the 21-point game was a pretty jarring wake-up call. Yes, it was the first time on the road for a young passing game, but OSU has a lot of experience elsewhere. This year won't be an easy one for Oklahoma State, but making Wes Lunt throw the ball 60 times a night isn't the answer. Dishonorable mention: Kansas.

Worst quarter: Oklahoma State's fourth quarter. The Cowboys were still in it after a Quinn Sharp field goal cut Arizona's lead to 37-31 entering the quarter. However, turnovers and an inability to stop the run turned it into a borderline embarrassing loss. The Cowboys were outscored 22-7 in the quarter and left the desert as losers in their first major test. Rough way to close the outing. Dishonorable mention: Kansas' fourth quarter, when the Jayhawks entered with an eight-point lead and lost.

Best quarter: TCU's first quarter. The Frogs scored on the very first time they touched the ball in the rebuilt Amon G. Carter Stadium. Not bad, eh? Deante' Gray scooted 70 yards to return a punt for a score, and by the end of the first quarter, the Frogs led 28-0, with a rushing touchdown, a passing touchdown, a special-teams score and a defensive score on a 28-yard Elisha Olabode interception return. That'll work.

Oddest performance: Malcolm Brown, RB, Texas. Brown's not exactly a bell cow, but he's the featured runner for the Longhorns. Mack Brown said Malcolm Brown was healthy, but the sophomore and Longhorns leading rusher a season ago carried the ball just two times for 5 yards on Saturday. Three other players, including QB David Ash and freshman RB Johnathan Gray, had more plays called for them. What's up there?
