Philadelphia Freedom (which is the default name of one of the teams in DDS: Pro Basketball, and which always puts the corresponding Elton John song in my head)
Sacramento Solons (alliterates, is topical in that "Solon" is an old word meaning "lawmaker" and Sacramento is the capitol of California, and it's historical in that it's been used by prior Sacramento ballclubs)(the mascot could be a Cylon from Battlestar Galactica)
Kentucky Colonels ("it's a reference to the valor of the residents and not fried chicken! We promise!")
Birmingham Barons (alliterates and IIRC the name of Willie Mays' first team)
Montreal Expos (come on, you know you want to)
Vancouver Pig Warriors (a reference to my favorite
moment in US/Canadian history)
