We drew 14,000 last year and over 18,000 for our previous non-UIC opponent in 2013 (13,000 for the last UIC game). We sold it out vs. Gonzaga a few years ago.
I'd say it has a lot less to do with how big of a draw we are in our largest city and a lot more to do with Illini fans sending a loud and clear message to our administration. Our DIA is a mess, and they don't seem to care. I don't blame the fans. I missed that game for the first time since 1998.
Our fans are sick to their stomach, and they should be.
