Halftime update: Tech 35, KU 14

Posted by ESPN.com's Tim Griffin

LAWRENCE, Kan. -- The biggest question coming into the game was how Texas Tech's defense would play against a good offense.

After 30 minutes, defensive coordinator Ruffin McNeill's unit has answered that question with ringing authority.

The Red Raiders have contributed three third-down stops and a critical fumble recovery to provide the difference in Tech's convincing 35-14 halftime advantage over sputtering Kansas.

Tech's defensive front has been able to pressure Kansas quarterback Todd Reesing with a four-man rush, contributing three third-down stops and a sack that turned into a fumble that was turned into the Red Raiders' final touchdown drive.

The Red Raiders have played offense with cold-blooded efficiency, scoring five touchdowns on their first five possessions in the half before failing on their final possession at the end of the half.

Tech quarterback Graham Harrell has barely been pressured. He's taken advantage of his pass blocking to complete 22 of 26 passes for 274 yards for four touchdowns, involving seven receivers in his mix.

And Tech's underrated running game has provided a lift with 87 rushing yards and 7.9 yards per carry to keep the Kansas defense off balance and keep Kansas defensive coordinator Clint Bowen harried for an answer.

For good measure, Harrell even contributed a season-best 13-yard scramble that helped extend a scoring drive early in the second quarter.

Tech walk-on kicker Matt Williams is quickly becoming a footnote -- literally and figuratively. His only action has been on five extra points and he's converted all of them without a problem.
