SO Utah HC is the "Yeti" without calling themselves the Yeti. Fair enough. It reminds me a lot of the Kootenay/Winnipeg Ice logo - the head is just pointed more to the side and not as much towards the front. Given that the team rebranded to the Wenatchee Wild maybe that's not such a big deal, but if they're really sensitive about trademarks that could be a concern.
Outlaws seems like the real outlier here - the logo looks quite generic, and doesn't go with the black-and-blue colour scheme.
The Mammoth - eh it's fine. Looks good even.
My money is still on Tuah HC, more so after seeing the logo.
