Here are some stats to compare. I think we will win because of our defense. We'll have some success on offense but I don't think we'll see a lot of 30+ yard runs. Hopefully I'm wrong and there are several.
Rush Defense
#19 Texas: 2.63 yards/attempt, 198 yards/game
#63 Idaho: 4.39 yards/attempt, 151 yards/game (360 by Nebraska)
#106 Washington: 5.35 yards/attempt, 207 yards/game (383 by Nebraska)
#111 Western Kentucky: 5.68 yards/attempt, 211 yards/game (289 by Nebraska)
#116 Kansas State: 5.82/attempt, 246 yards/game (451 by Nebraska)
Rush Offense of Texas opponents
#17 UCLA: 5.17 yards/attempt, 223 yards/game (264 against Texas)
#87 Oklahoma: 2.87 yards/attempt, 123 yards/game (124 against Texas)
#102 Rice: 2.83 yards/attempt, 103 yards/game (88 against Texas)
#103 Texas Tech: 3.52 yards/attempt, 103 yards/game (-14 against Texas)
#120 Wyoming: 2.20 yards/attempt, 69 yards/game (58 against Texas)
The moral of the story is, Nebraska hasn't played a good run defense, and Texas hasn't played (stopped) a good run offense.
