I like Native American references when it's accurate and the tribe supports it. Like the FSU Seminoles, but I don't really know my geographical tribes that well. The Phoenix Apaches? I also like various cultural and ethnic names like the Celtics so the Utah Mormons or the Utah Missionaries would actually be something I'd like. It may sound odd to you, but I respect it. It takes a certain amount of guts to do what they do rain, sleet, or shine.
