Thing is, that obsession seems to go both ways with a few Husker fans. We've just joined a conference that already has three of the top seven all-time winningest football teams, yet I see five times more threads about Iowa than about Ohio State, Michigan and/or Penn State combined.
There's a small section of Husker fans, notably those who live either in Iowa itself or along the Nebraska/Iowa border, for whom hating on Iowa is an obsession. For the most part, those of us who live outside those areas don't care. All this focus on Iowa is mind-boggling, especially when we're in a division with Michigan. And yet nobody wants to talk about Michigan.
