Been to a Cardinals game lately? If so, then you should know the relationship between attendance and the quality of the product you are watching.
During the Spoonball era, we enjoyed a combination of good teams playing in a strong conference against schools with national name recognition. We won enough games to make life very interesting for the fan base.
Majerus coached his players up to a high level, nationally recognized. Even then, I don’t recall any sellouts at Chaifetz.
One way to boost attendance would be to stop televising home games. Not so sure that would be a popular idea.
