They're my best friends. One of them comes to almost every football game, but they don't come to any basketball games. It's not a thing of school allegiance at all. I don't think UVU pride is an actual thing aside from maybe 20 people.
I think its just an out of mind out of sight factor. If the city of Provo would do more street banners like they do around center street and more adverts around town, I think it would increase these non BYU campus fans. Plus, not losing to trash teams would help.
