Dang. Lots of hate against "Euro" style names. Which I understand somewhat. For example, why the heck is Salt Lake, Real Salt Lake. There's never been a monarchy in Utah as far as I know.
However, I would actually argue that these names are not "Euro-style" as much as the soccer nomenclature. It's not as much as American vs Europe, it's soccer vs football, baseball and hockey. Is it wrong to say that soccer originated in England and teams are named similarly, while baseball originate here and teams in Japan are named in similar "American-style?"
These names can be quite lazy, but I don't see them as inherently wrong.
Also, seems like there is a lot of confusion between team/club/organization names and team nicknames. Some people are talking about nicknames like Archers and Stars, while others are talking about 1764 St Louis. FC Schalke 04 is the name, but they have nicknames of the "Royal Blues" and "The Miners"
