NE FB is the only show in the state.
They do not fill the stadium with only folks that live in Lincoln.
The population of the Twin Cities is far greater than that of Madison.
If the Gophers were the only show in the Twin Cities they probably would draw better. NE draws very well despite a mediocre record over the last fifteen years.
The underlying mistake in logic is that the WI stadium is mostly filled with folks that live in Madison.
It is not.
WI draws from all over the state as NE does.
You're kidding about Nebraska, right? If the Gophers had their record, attendance would change dramatically. This is starting after the Huskers' THREE national championships in the 1990s. They even won eight games or more in two of the four "dreadful" Bill Callahan years. (Numbers at the end are Nebraska's finish in the final coaches poll and AP poll. I wish I knew how to format better on this site.)
