STILLWATER, Okla. (AP) — Brandon Weeden threw for 288 yards and five touchdowns before being pulled out of a lopsided game before halftime, and No. 6 Oklahoma State matched its highest scoring total from the last 94 years in a 70-28 rout of Kansas on Saturday.
Jamie Blatnick recovered a fumble and leaped to tip an interception to himself for two of the Cowboys’ four first-half takeaways, and Oklahoma State (5-0, 2-0 Big 12) scored touchdowns on all eight of its possessions before halftime against the nation’s worst defense.
Kansas (2-3, 0-2) came in allowing a Bowl Subdivision-worst 44.3 points per game, and Oklahoma State had already surpassed that total with 4 minutes left in the second quarter on Weeden’s second TD pass to All-American receiver Justin Blackmon.
That score made it 49-7, and backup Clint Chelf tacked on a 3-yard TD pass to Hubert Anyiam with 12 seconds left before halftime to give OSU 56 consecutive points.
Chelf added 206 yards on 14 for 21 passing with two TDs. The 494 yards passing allowed were the most ever for Kansas, surpassing the 481 by North Carolina State — mostly by Philip Rivers — in 2003.
Weeden had the most accurate performance ever by an Oklahoma State quarterback, completing 24 of 28 passes for 85.7 percent. That was just a few percentage points better than Zac Robinson’s 85.3 percent mark against Baylor two years ago.
Weeden came in as the nation’s second-leading passer, trailing only Houston’s Case Keenum with 398 yards per game, and will drop off in that category despite a brilliant performance. Of his incompletions, one was dropped by Blackmon on a screen pass and he purposely threw one away out the back of the end zone.
By halftime, he was already wearing a black ballcap backward on the sideline.
The Cowboys scored their most first-quarter points in the modern era with 35 and tied the school mark with 56 points in a half.
That doesn’t include early blowouts, including a 117-0 shutout of Southwestern Oklahoma State in 1916 that was the last time the program scored more than 70 points in a game or a 134-0 win against Phillips that represents the school scoring record.
The only time OSU has reached 70 points since 1916 was a 70-7 win against Southern Illinois in 1973.
The biggest thing the Cowboys had to fear coming into the game was that it could be a trap ahead of road games at No. 11 Texas and Missouri the next two weeks. The Pokes came in as the nation’s sixth-highest scoring team (46.8 ppg), second in passing (415.5 ypg) and third in total offense (571.8 ypg).
The Jayhawks struck first, receiving the opening kickoff and then driving 80 yards to go up 7-0 on Jordan Webb’s 10-yard touchdown pass to tight end Tim Biere. Toben Opurum sped around left end to sack Weeden on the Cowboys’ first snap.
After that, the highlights were few for Kansas.
Oklahoma State needed less than 2 minutes to respond with seven straight Weeden passes, the last one a 12-yard TD toss to Josh Cooper.
Blatnick then recovered Tony Pierson’s fumble on the Jayhawks’ next offensive snap, and OSU cashed it in three plays later on Weeden’s 24-yard screen pass to Blackmon.
Anyiam also caught two scoring passes, Michael Harrison and Isaiah Anderson caught one apiece and Jeremy Smith rushed for a touchdown in his ninth straight game for Oklahoma State.
Coach Mike Gundy pulled his starters for the final drive of the first half and didn’t flinch when Kansas blocked a punt and scored just over 2 minutes into the second half.
Webb completed 25 of 36 passes for 316 yards with two touchdowns, two interceptions and a fumble lost in the 11th straight road loss for the Jayhawks, with the last six under second-year coach Turner Gill.
