Aside from individual miscues Saturday, Oklahoma battled breakdowns on a group level as well. These were the most damaging:
Oklahoma defensive coordinator Brent Venables says there was no big mystery to why Colorado beat the Sooners Saturday.
"I know how we lost. We let them run the ball,” he said. "That's it.”
Colorado came in averaging 123 rushing yards per game, including a 359-yard performance last week. But on Saturday, the Buffaloes rushed for 161 yards on an OU defense that prides itself on stopping the run.
"They started running the ball on us,” OU safety Nic Harris said, "and after that, they could do whatever they wanted.”
For the first time this season, the OU blockers didn't look worthy of the preseason hype they received as one of the best lines in the country. The physically imposing front five struggled to open holes, especially early in the game.
After the 7:31 mark of the second quarter, just two of 15 carries by OU running backs went for more than nine yards.
Quarterback Sam Bradford was sacked once and pressured on other occasions.
