There are 2 stadiums in the ACC that are smaller than Nippert stadium. I highly doubt stadiums have much to do with who gets in and who doesn't. Beyond that, like I've pointed out on a few other threads, UC has a preliminary deal with Paul Brown Stadium (Bengals stadium) in the event that they move to a large conference, they've played a few games there already against big opponents (WVU, Oklahoma, Louisville). i realize it sucks, and it puts me in a weird spot since i graduated from UC and now attend USF, but it is what it is, if the ACC isn't going to happen, we need to push for the Big 12, which honestly might be more stable in the long run.
Sorry, but those smaller stadiums have indoor plumbing, not port-o-lets.
If this is true FSU will do EVERYTHING it can to get the hell out of the ACC, which has always catered to basketball. And I agree with you that the ACC will soon be the the new BIg East.
