31-14. Texas
Teams have had success moving the ball the last quarter of the season or so, and I really don't see Texas making the same mistakes that others in the north made. OU's turnovers to me are as much a fluke as Nebraska's were against ISU. So when you break it down, Texas has better players than every team NE as played. And those teams found success on Nebraska, but seemed to always make costly mistakes (i.e. penalties and turnovers). If Texas does not make those mistakes they should be able to put up 28+ pts.
Nebraska on the other hand has struggled mightily all season. Nebraska is dead last in offense during conference play. Scoring fewer touchdowns then every team except Baylor. In other words this team thrives on others mistakes (turnovers and poor special teams)
Point blank, I don't think Texas turns the ball over multiple times, if at all. And I don't believe Nebraska, unless they pull every trick play in the book, (and they work) can score over 17.
