It does not seem like you have much of a choice if you are born and raised in Nebraska. I mean, there are a few but are far and in-between. Just about everyone here is a Cornhusker.
It doesn’t matter if your family went to the university or not. Just about everyone loves and follows the team from Lincoln. Very little has changed in that matter over the years.
From roughly 1965 to 2001 the University of Nebraska Cornhuskers were a behemoth on the gridiron. That is four decades of dominance that influenced multiple generations of fans.
