I don’t agree with Yetis. The Yeti is a mystical creature much more identified to a much more wintery and cold location than Utah state.
I think that a the name of a team should represent something specific to the state of Utah like:
Utah Canyons
Utah Goats
(fearless mountain goats). I can pictured a goat on the top of a peak.
and so on. There are many more names more specific to the state of Utah
