How about these for expansion or rebranding:
Nashville Fiddlers... but the logo will be a Brown Recluse Spider aka a Fiddler-- double bonus points for a spider logo with a fiddle would be extra awesome!
St. Louis Spirits... a ghost or phantom type of logo
Memphis Pharaohs... stadium called the Pyramid and team has an Egyptian motif
(North) Texas/Pennsylvania Wildcats/Wildcatters... can use the oil rig (Oilers) in the logo with a wildcat wearing a hard hat!
Santa Barbara Stingrays
Vegas Bandits... as in one arm bandits!
Charleston (SC) Tridents... the Trident nuclear submarines were built there
Portland (OR) Webfoots... found this reference in an old encyclopedia. The term has a colorful history!
San Antonio Siege
Tallahassee Starfish... a coral and blue uniform
Birmingham Vulcans... statue of the Roman god of fire Vulcan in city!
Birmingham Minotaurs... of course they play indoors in the Labyrinth!
San Jose Seahorses
Alburquerque Roadrunners.... you have the Coyotes so it could be a Cowboys/Redskins rivalry type of deal
