I have heard in various places that modern copyright laws will prevent use of existing names from other sports, which if true would nix Grizzlies, Lakers, Raptors, Eagles, etc... I also agree 100% that Yeti(s) is very cringey.
I feel like they should steer clear of animal names, they are mostly very generic, though easier for mascots/general family friendliness, and do something more unique.
Suggested in the previous threads, but Utah's ties to the Wild West era could make names like Outlaws, Bandits and Renegades work (though a few of those would be very generic as well).
For me, the best names I've heard so far are:
(Non-animal): Rebels, Racers
(Animal): Dragons, Sidewinders
