I know the EQP is a Ute fan, but he's really chill and doesn't seem to be a die-hard (at least anymore - maybe he was at one point).
Another guy in the ward brings a bag with a Ute mullet decal on it, but he also went to BYU for his BS and I don't know if he's even a sports fan.
Other than that, I don't hear about or talk to any Utes that I know of. If they are there, they are in hiding. I think lot of this is because I'm in a ward highly concentrated with graduate students and academics, and BYU has a lot of students leave for graduate programs to other schools (much more than Utah does, I presume).
BTW - I got my Masters at Utah, but I never tell people that upfront. I just let them assume I went to BYU since I'm a huge BYU fan.
