I agree with most of the remarks here, but I don't think I'd go so far as to say that Akron draws poorly for basketball. They usually have decent sized, involved crowds. I like going to games there and at Kent for that matter.
Jeff, I see Akron and Kent basketball box scores in the ABJ. A typical Akron home crowd runs between 3,000-4,000. Rhodes Arena seats about 6,500. Given that Akron has rolled up 20+ wins for close to a decade, I'll stick with saying the Zips draw poorly and that campus culture is a major culprit.
It just depends on what your scale is. Compared to Ohio and Toledo, they draw poorly. But Akron's attendance in a slightly down year is just behind Buffalo's for third place in the MAC.
I think both culture and winning clearly have a part in attendance. With Ohio having a winning tradition in basketball and a setting that leads to high student and alumni attendance, Ohio dominates the MAC in basketball attendance. In football, where the tradition is much poorer, Ohio's attendance is much more average, but I think even before the Bobcats were any good at all, attendance wasn't bad because of the way students and alumni connect.
