Ok this may sound insensitive but I’m trying not to be. Why not the New Orleans Hurricanes? I mean it would be a Batman type thing. As a kid Bruce was scared of bats so when he was thinking of ways to intimidate his enemies he chose the bat as a symbol. Katrina was as big and scary as they come. Completely kicked their butts. Why not use it to strike fear and kick the butt of everyone else? I think that would be an awesome idea and it would make a cool team name.
Be excellent to each other
