Oklahoma coach Bob Stoops said his biggest concern heading into the final five games is to find a way to finish games strong.
Missouri dominated the fourth quarter to win 36-27 Saturday night, handing OU its first loss.
"After giving up the touchdown right off the bat on the return, we fight back to lead 21-20 at the end of the third quarter," Stoops said Monday on the Big 12 teleconference. "Really our defense has given up only 13 points.
"But in the fourth quarter as a team we didn't play very well. The offense has three three-and-outs and an interception and the defense gives up 98 yards rushing and two touchdowns in the fourth quarter. We have to keep our consistency and play better in the fourth quarter."
The Sooners have been outscored 77-30 in the fourth quarter. Because it's been a season-long issue Stoops asked why it's been so difficult to finish strong.
"The schemes don't change in the fourth quarter," Stoops said. "That's where it's kind of frustrating. Everyone's game plan is out in the open by the fourth quarter... We'll emphasize some things in practice and how we're trying to do it. In the end it's just maintaining that pace throughout the game.
"We'll try a few wrinkles in practice. You've just got to be able to play the same way throughout (the entire game)."
Missouri spread the field, consistently having success over the middle where the Tigers gained a lot of their 486 yards.
"In our soft zones in cover three we weren't very good," Stoops said. "Tackling a time or two (was an issue). We had a busted alignment and a couple of poor calls in what we asked our guys to do. All that together we feel we're capable of playing better. But I also thought Missouri's execution was excellent."
Three turnovers were pivotal. Landry Jones threw two interceptions. On both occasions Jones locked onto a receiver.
"He's still so young," Stoops said. "As much as anything a guy is always a byproduct of the guys around him. The other night we got pressured a time or two where you'd like to see him make a better decision and take better care of the ball a little bit better. That's a big issue.
"The other day we had three turnovers, two of them in the red zone. You're just not going to win when you do that against a good football team like Missouri. Taking care of the football is always a big issue."
One area that's plagued the Sooners all season is the defense has surrendered more plays of 20 yards than any team in the Big 12. Stoops said the season opener defensive backs failed to turn and find the ball. Other times it's been alignment issues or busted coverages.
"Each game is a little different whether it's guys in position to make plays didn't make them or had their back turned to the football on some deep passes," Stoops said. "Here lately a time or two we got caught in a busted alignment like against Texas on their one touchdown run in the first half.
"It's a little bit of everything, whether it's a busted alignment or a missed tackle, having our back to the quarterback, not seeing the throw."
This week the Sooners host Colorado, which lost its starting quarterback (Tyler Hansen) and leading tackler (Jon Major) to season-ending injuries in Saturday's loss to Texas Tech. The Buffaloes defeated Georgia and Hawaii but are 0-3 in conference play.
"It seems anybody can beat anybody for the most part," Stoops said. "There is a ton of parity. It will be tough. It will be a dog fight to the end with everyone."
