In the end Florida is a football state, so comparing a potential football OCS to the Sun Dome is apples to oranges.
That, and the fact that the basketball team also keeps losing to the likes of IUPUI will not generate interest among students.
But the students at least will come out to watch football if our team isn't total garbage.
The student section was consistently packed when we had a winning team (see attached pic - Cincy 2017). And that's taking into account the hassle of getting to Ray Jay as a student and all the potential risks involved with drinking etc. If the students come out to Ray Jay, they definitely would come out to an OCS.
The real problem is the casual fan. They REALLY dgaf, even with a winning team.
