I think its seriously unlikely that Iowa gets "killed" by Nebraska
Nebraska gave up 35 points and 500 yards vs Illinois
Nebraska gave up 36 points and 480 yards vs Ohio State
Nebraska gave up 28 points and 473 yards vs Minnesota
Nebraska gave up 34 points and 487 yards vs Northwestern
Nebraska gave up 41 points and 533 yards vs Wisconsin
Nebraska gave up 42 points and 516 yards vs Purdue
Nebraska gave up 56 points and 491 yards vs Michigan
Throw the Michigan State game out the window. The injuries, the weather, the drops, the Sparty backup QB completed 15 of 41 passes.
Iowa should score often against Nebraska.
