String of home game sellouts dating back to 1962 or something like that...even in lean years
Yes. The Cornhusker State is very proud of that. That streak has been in peril a time or two in recent years with the team looking so poorly... but they manage to keep it going even if warm bodies are not always in all the seats.
There is something to be said for a shared rallying interest like sports for a State. The closest thing for the State of Ilinois is the Illini Basketball program. Baseball fans are divided amongst the Sox, Cubs, and Cards. Much of the State doesn't care about the Bears or Bulls or Blackhawks. But with the legacy success for so many past years of the Illini roundballers they represent the State well and can bring it together in ways the other teams haven't. (Even with some possible resistance in pockets of the CIty of Chicago).
If the Bears ever got their act together they would pick up a lot of interest around the State that has drifted away for so many years.
So much of the State of Illinois wants and craves to see great success from the Illini footballers. That's an untapped resource ready to break open.
