Yes! I looked this up. It's actually very impressive in retrospect... How did I not notice this before?
Starting 11/7/09 versus Oklahoma, the Huskers are 19 for 21 at home. They beat 10 out of 12 ranked teams in that span, and beat every unranked team they played.
The only two losses in the last three (calendar) years were to Texass by 7 in 2010, and Northwestern by 3 last year.
