PTSD from BYU’s “tan” era.
Also, not a fan of the Utah Mammoth. A mammoth is a hairy prehistoric elephant. Hard to do cool branding with that. Same reason I don’t like the Utah Caribou. Sucks for branding. Look at the Milwaukee Bucks for an example of how hard it is to create a cool brand with an antlered animal. I don’t think an extinct animal with tusks would fare much better.
