Said defensive coordinator Brent Venables: "We didn't play with the kind of discipline and purpose we have all year. And they're good enough to expose you and they did."
To open the second half, Tech scurried 91 yards down the field in six plays to go up 24-6.
The backbreakers, though, were still to come.
With OU desperate to get its offense back on the field, the Red Raiders began an 18-play drive late in the third quarter that would cover 80 yards and more than 7 minutes.
Only one play on the methodical drive — Baron Batch's 21-yard touchdown scamper — went for more than 12 yards.
Tech even overcame a pair of 15-yard penalties along the way.
"Very disappointing when they had a long drive like that and you can't stop them," said defensive end Jeremy Beal. "They kicked our butt. Scoring on an 18-play drive? That's kicking your butt."
But the kicking wasn't done.
Later in the fourth quarter, the Red Raiders came back and hammered away with a 14-play, 82-yard drive.
After quarterback Taylor Potts' intentional grounding penalty, Tech faced second-and-17. But on the next play, running back Eric Stephens beat OU cornerback Dom Franks to the corner and dashed 30 yards down the sideline for the first down.
Two plays later, Stephens finished off the drive with a 4-yard touchdown run between the tackles.
"We just got beat," McCoy said. "No certain (assignment) we didn't make. No certain call we didn't call. Just got beat."
