Eh.. closer to aggie than Tennessee, but a similar lack of attachment to reality and their place in college football history. Its a non-full cult, version of aggie. Maybe the Etsy version. People care and will watch Tennessee, though its admittedly extremely regional. Aggie and Iowa both think the world cares about them, they are often, incorrectly voted into the top 25, both think they're a blue blood, yet, most people care far more about watching them when they are playing, ya know, an actual blue blood. Iowa has no cult, fake army or jenga death tributes, but they are similarly devoid of reality regarding who does, or more importantly does NOT give a shit about them. Which, in both cases, is most of the US.
ISU, Wisky and Goofers love to watch them lose, like Texas (and LSU is starting to) sops up aggie tears with bread (so delicious), and because of their trumped up, errant ranking, the media plays them up as a "dangerous underdog" against ranked, real blue bloods.
Some of that applies to Tennessee but not the majority.
