Advanced analytics has Indiana being a top 10 team. I personally don't think they are, but by the numbers, they have one of the best passing attacks in the country.
Nebraska was atrocious in the secondary against Illinois. Even on plays where Nebraska got pressure forcing a bad throw, Illinois had wide open receivers downfield.
Indiana has a much better offense than Illinois, so Nebraska will have its hands full.
As for the topic, I had Nebraska at 6-6 before the season and I'm leaning towards 6-6 now. Finding 3 more wins may prove difficult, as it will require Nebraska to win close games. Something they have proven incapable of doing.
