Always hard to tell with OU-Texas. I haven't got to see Texas [lose] as much as I would like this season, but I've watched them a couple times. Their defense is good and seems to get better every week. OU will definitely have a hard time running the football, at least in the traditional sense. OU was missing a guard last week (Ford) and it definitely slowed down the run game...not sure when he's supposed to come back. The goal line stand that Army had shows that the line isn't quite what it was last season. The loss of Anderson is huge as well. His ability to catch the ball out of the backfield covered up a lot of deficiencies. OU's receivers are awfully good though, so as long as they don't commit turnovers, I do expect OU to move the ball and put up enough points to win.
I haven't been extremely impressed by Texas' ability to run the ball, but their passing attack has improved and Ehlinger will make plays with his feet. No one knows which OU defense will show up. I could see them holding Texas under 20, or giving up over 40. If Texas can limit turnovers, control the clock, and completely remove OU's run game, they'll have more than a chance. If OU gets a run game established and takes away Texas' ability to run, it could be a blowout. Special teams and turnovers, like always, could have a huge impact on the game.
