Anchorage Genies: Named in honor of Genie Chance, a reporter and later politician who spent nearly 24 consecutive hours reporting on the 1964 Alaska earthquake. This is probably way too deep of a cut, but I think it would be a really cool brand.

Detroit Ambassadors: Re-upping this from the AltBA; named after the Ambassador Bridge.

Edmonton Trappers: There used to be a lotta fur trading up in that neck of the woods.

Milwaukee 48ers: Named after the German immigrants in Milwaukee, many of whom participated in the 1848 revolutions. Also gives us a Niners/Sixers type name.

Ottawa Barons: Named after the lumber barons prevalent in the second half of the 19th century. It also sounds very parliamentarian. (If this is nixed because of Cleveland, lmk and I'll change it.)

Saskatchewan Prairie Dogs: Saskatoon is nicknamed "Paris of the Prairies," and what's more prairie than a good old prairie dog?
