Halftime Analysis: Texas 21, Ok. State 17

STILLWATER, Okla. -- Texas coach Mack Brown was curious to see how his team reacted against a solid Big 12 team. In the first half, the answers were mixed. Offensively Texas was solid. Defensively the struggles from Ole Miss continued.

Stat of the half: After scoring a combined 35 points in the first quarter, all these two teams could only manage three points in the second quarter. Oklahoma State clearly struggles in second quarters. The Cowboys failed to score against Arizona in that loss and only scored three against Texas. This was the first time that Texas has failed to score in the second quarter.

Player of the half: Oklahoma State running back Joseph Randle has devastated Texas in the run game. The junior took his first handoff and went 69 yards for a touchdown. Randle had 103 yards in the first quarter and continued to carve up Texas in the second, finishing with 147 yards and a touchdown. Oklahoma State had 168 rushing yards in the first half.

What's working for Texas: David Ash has continued to play with poise. The sophomore has directed two scoring drives and been accurate on most of his downfield passes. Ash, who has two touchdown passes, should have had another, but a 40-yard toss was dropped by Mike Davis in the end zone.

What's not working for Texas: The Longhorns are once again failing to tackle. Both of Oklahoma State's first half touchdowns came as a result of missed tackles by safety Adrian Phillips. The first was the 69-yard run by Randle. Phillips had Randle wrapped up at the 48, released hum and watch him run the next 52 yards. On the next touchdown, Phillips hit receiver Josh Stewart at the 23 but bounced off, getting injured on the play. Stewart scooted into the end zone from there.

What Texas needs to do to stay ahead: Continue to get a rotation of fresh players in on defense. The Longhorns are down four potential starters on that side of the ball. Defensive tackle Brandon Moore (virus) and linebacker Jordan Hicks (hip) did not make the trip. Phillips was hurt in the game. Defensive tackle Desmond Jackson also was hurt. Texas has had to use true freshman Malcom Brown at defensive tackle and little-used junior Kyle Kreigel.
