As a fan, I noticed the bad blood by Nebraska fans, maybe 2-3 years into our move to the Big Ten. I never really noticed this from Iowa fans, but I have seen lots of guys obsessed with Iowa on our board, for years now.. so to me, this was really started by the Nebraska fans who were in a new conference and assumed they would beat Iowa, and when we started losing to them, they made this an issue, plus we didn't have any rivalries.. So Iowa was the closest state and hence this was entirely fan created on the Nebraska side IMO.
The crap about not shaking hands, goes completely against the culture at Nebraska and we deserved to lose because of that 1 thing alone. Each of those team captains should be relieved of those positions. I don't know what kind of culture Rhule is running down there, but that is completely unacceptable. Matt Rhule will get a ton of hate mail for that.
