Core fans are the ones there through thick and thin ... Not sure what adjective you can use to describe any fans being eroded right now but core would be inaccurate.
I have to wonder that that core number is?
Core would be those that continue to donate a decent sum, buy tickets, attend games, buy gear? Re-arrange schedule to watch or attend roadies?
I have to believe "core fan" is being redefined weekly, too.
So far that is what describes us. Although I did sell our Miami away game tickets last year. We are still making the trip to Houston. We are core fans. Plan on being at all the home games. Our friends know that it is nothing personal, but if the Bulls are at home we aren't available.
