I think in the past you're right. When UNI was humming as a department and Iowa was down, think late 00s, that was more the case. UNI has done such a poor job of marketing and has gone from being an elite FCS/Mid to merely good thanks to a shrinking budget that we don't have casuals anymore. We're down to the 8000 UNI football fans and 3500 UNI basketball fans. That's it.I'm not saying there won't be a bunch of Panther ones. But there will be a ton of Iowa ones (and flags too). I've literally driven right down Hudson Rd multiple times on gamedays in Cedar Falls and seen this. You don't have to like it but it is what it is. I get there are Cyclone fans in there (and growing) but there's no denying the major Hawk contingent among "Panther" fans.
Plus there's that contingent (majority?) of the Iowa base that just feels the need to cheer against Iowa State no matter what and they like to go the fake UNI fan route to do it. Believe me, we hate it too.
