Have Husker relatives on Mrs. Billd's side of the family.
Prior to joining the B1G, there's at least 1 if not 2 generations of Big Red fans that viewed any matchup with Minnesota as an automatic W. Frankly, all available data supported that expectation.
Fast forward to now and there's huge dissonance inside that Husker cranium around Minnesota. The genome says that Minnesota = BAD...while the B1G record and other data indicates Minnesota > Nebraska.
Losing to us really eats at them. When they look in the mirror, they see the big L on their foreheads, with losses to Minnesota a big part of that.
