What I always do is spell 'em backwards and see how weird they can get.
Buffalo=Olaffub (If the Red Wings were in Buffalo we'd call 'em the Buffalo Wings ) Colorado=Odaroloc Ottawa=Awatto Boston=Notsob Detroit=Tiorted Minnesota=Atosennim Calgary=Yraglac (looks like the name of some Slavic town or something) Columbus=Submuloc
Now for rearranging the letters... Los Angeles=Lose angles Anaheim=Ah, Maine! San Jose=Jon's seas Montreal=La remote
I bet nerds up in Edmonton call their team the Edmonton Eulers! LOL (If you don't get that, Euler was a famous mathematician and his last name is pronounced "Oiler")
I know they don't have a team, but... Saskatoon=Nootaksas (sounds like "new taxes" lol)
