Looking at the two loss teams ahead of Nebraska, I think they make a significant jump after they beat a ranked Wisconsin at home. Right now they have 7 two loss teams in front of them. I believe they should jump all of those teams with a quality win against Wisconsin.

But looking at the two loss teams ahead of them:

-Georgia has to play Auburn, Nebraska will jump the loser.
-Arizona plays ASU, Nebraska will jump the loser. They also have a tough one @ Utah.
-Kansas State plays Baylor, Nebraska jumps the loser. They also play @ WVU.
-UCLA still has USC and Stanford on their schedule. They need to drop one.
-Ole Miss plays @Arkansas and Miss St. They will drop one, Ark is due for a big win.
-Auburn besides @UGA still has to play @Bama. If Auburn beats UGA but loses to Alabama, Nebraska passes both UGA and Auburn.

Nebraska has a chance to be ranked anywhere from 8-10 by the time they play Ohio State.
