My personal choice would be the "Cleveland Fellers".
Cleveland Commodores (Commodore Perry inspired)
Cleveland Captains (the name currently being used by their Class A minor league team)
those are my two guesses
these are to be silly;
Cleveland Krakens
Cleveland Wildthings
Cleveland Burning Rivers
Cleveland Mud Hens
Cleveland Crowns (because it rhymes with Browns. No royal reason. Cincinnati is actually the queen city)
Cleveland Rocks
Cleveland Comets
Cleveland Komisars (well, ¯\_(ツ)_/¯ , republicans don’t win here. LOL)
Cleveland Circumlocutions (was trying to think of something long and obscure)
Cleveland Counterterrorists
Cleveland Cyborgs
Cleveland Cardiacs
