Big 12 scoreboard

Arizona 59, No. 18 Oklahoma State 38: Arizona defensive coordinator Jeff Casteel spent last season at West Virginia going against Dana Holgorsen's offense every day -- the same offense Oklahoma State runs. Casteel's defense figured out how to slow the high-powered Cowboys enough for the Wildcats to win Saturday night, intercepting OSU freshman QB Wes Lunt three times. Oklahoma State's defense allowed 500 yards and could not force a turnover playing without defensive coordinator Bill Young because of health reasons. Lunt started fast and led the Cowboys to a 14-0 lead, but his 440 yards passing and four touchdowns -- all caught by Tracy Moore -- were not enough to keep up with the Wildcats in the upset.

No. 21 Kansas State 52, Miami 13: After the Wildcats struggled for three quarters to put away Missouri State on opening weekend, few could have seen this coming. The K-State win wasn't as surprising as the manner in which it happened. Bill Snyder's squad was simply dominant, finishing with 290 rushing yards while allowing only 39. It was 52-6 before the Hurricanes added a score in garbage time.

Iowa State 9, Iowa 6: Iowa State was far better than the score indicated, and Steele Jantz looked calm and composed for long stretches. But three turnovers inside the red zone kept this one close, and it wasn't over until Jake Knott grabbed a late interception to seal it. Ugly or not, ISU will take it, as the Cy-Hawk Trophy will stay in Ames for another year. The Cyclones, underdogs in their first two games, are 2-0.

Rice 25, Kansas 24: A last-second field goal gave the Owls a road win at Memorial Stadium, and it looks like another long season might be in store for Jayhawks fans. The passing game struggled mightily, and the defense yielded 403 yards. If Rice can put up that sort of yardage, imagine what the Big 12's high-flying offenses might do to KU.

Texas Tech 58, Texas State 10: Texas State opened the season with a convincing win over Houston, but Texas Tech proved to be too much, earning an easy win on the road. Twelve Red Raiders caught at least one pass, and QB Seth Doege threw for 319 yards and five touchdowns and no interceptions. The 58 points was the most allowed by Texas State in a home game.

No. 20 TCU 56, Grambling State 0: The Horned Frogs opened their renovated Amon G. Carter Stadium in style, building a 28-0 lead by the end of the first quarter and polishing off a shutout in the second half. QB Casey Pachall was 9 fo 9 for 201 yards and three touchdowns before heading to the bench. 

No. 5 Oklahoma 69, Florida A&M 13: After looking weak in the season-opener at UTEP, the Sooners had few problems dispatching FAMU in Norman. RB Damien Williams electrified the home crowd, finishing with 156 yards and four touchdowns on 10 carries. Oklahoma moved the ball almost at will, averaging 9.5 yards per pass and 8.5 yards per rush.

No. 17 Texas 45, New Mexico 0: This is what Texas wants to look like -- a dominant defense and another solid mistake-free outing by QB David Ash. Ash threw for 221 yards and two touchdowns on 16-of-22 passing for a balanced Longhorn attack. Texas had 11 receivers catch passes and three running backs score, led by Joe Bergeron, who ran for 49 yards on 11 carries.

Play of the day: Iowa State outplayed Iowa all game, but three turnovers inside the red zone kept it closer than it should have been. Down 9-6, Iowa was driving in the waning moments and was on the edge of field-goal range. But the Cyclones' Jake Knott secured the Cy-Hawk Trophy, picking off Iowa QB James Vandenberg with 1:11 left. It was one last salvo in what was a strong all-around performance by Iowa State's defense.

He said what? Miami coach Al Golden after his team was utterly embarrassed by K-State: "They were excellent. They beat us in all three phases. They outplayed us, outcoached us, starting with me, and that's it. No excuses. They deserved to win."

RapidReports defensive star of the day: The Iowa State defense. To call the Cyclones' effort in the Cy-Hawk Trophy game heroic might sell it a bit short. Both times Iowa drove to the red zone, the Cyclones held tough and forced field-goal tries. The Hawkeyes managed only 304 yards of offense. Vandenberg threw two picks.

RapidReports offensive star of the day: QB Collin Klein, Kansas State. This just in: Klein can pass -- and he's accurate. Klein sent shivers down the spines of every Big 12 defensive coordinator with a new-found accuracy Saturday against Miami, going 9 of 11 for 210 yards and a touchdown. Klein was his usual self running the ball as well. He had 71 yards, too many broken tackles to count and three rushing TDs against the Hurricanes. Other than a jump-ball interception -- on a great defensive play -- and a head-scratcher play-call that saw Klein fumble on a behind-the-back-backward jump pass to WR Chris Harper (it was as ugly as it sounds), Klein made all the plays and showed K-State could have a more balanced attack this year. 

His seat is getting uncomfortable: Charlie Weis, Kansas. OK, it's only two games into his tenure, and given the debacle that was the Turner Gill era in Lawrence, fans will likely have a bit of patience. But losing 25-24 to Rice at home is not exactly the sort of result that gives Jayhawks fans any sort of optimism that the future will be any better than the recent past.

A possible spot on the bench for: QB Dayne Crist, Kansas. Crist followed Weis after the two were together at Notre Dame, and so far, the results aren't any better at KU. Crist threw two interceptions and only passed for 144 yards. The Crist-led passing game is the weak spot in the Jayhawks' attack, as Tony Pierson and Taylor Cox combined to rush for 199 yards on 34 carries.

Key number: 4.8 vs. 1.3. Kansas State chewed through Miami's defense, running for 290 yards on 60 carries -- an average of 4.8 yards per rush. The Wildcats' defense did quite the job of stopping the Hurricanes on the ground as Miami managed only 39 rushing yards on 29 attempts (1.3 yards per carry). The result? A blowout win for K-State.
