I think the stripclubs in town would give you enough names to compile a short lists:
Rhinos
Crazy Horses
Cheetahs
Sapphires
Flashdancers (maybe not :D)
Interesting that Kansas City is not on the list, I thought it was on the new NHL location short-list for a while.
The Las Vegas Basin & Range
The Las Vegas Horsts and Grabens
The Nevada Extensional Tectonics
The Flying Pucks.
Kansas City built the Sprint Center in the hopes of landing an NHL or NBA franchise. So what happens now is when a team wants a new arena, they use a threat of moving to KC as blackmail to get what they want.
In the meantime, the Sprint Center has become one of most-booked concert venues in the country, so at this point the city probably doesn’t even care if they get a sports franchise in there.
Keep in mind that, if the NHL Commissioner wants it, it would be illegal to bet on any NHL game involving the Vegas team, or any game (for example, the All-Star Game) held in Vegas. Note that the Silverton casino already does not take bets on any NHL games, as one of its owners is also part of the LA Kings’ ownership.
It’s not clear if the law applies to, say, futures bets on a Vegas team winning the Stanley Cup (it refers to “events”), although a similar situation prevents any Caesar’s group casino from taking futures bets on the Celtics winning the NBA title (if the Celtics do win, they pay off on the team they beat in the NBA Finals).
The Las Vegas Casino Buffets. Because expansion teams get eaten alive.
Las Vegas Elvises
Las Vegas Dancers
Las Vegas Wiseguys
Las Vegas Hustlers
This is a problem. I can’t think of any city with 2 of the same sports team where there isn’t an obvious “A team” and “B team”. The Mets are clearly the B team for baseball in New York, with the Yankees being the A team. In basketball, LA has the Lakers (A team) and the Clippers (B team).
After a quick look at the NHL teams, I’m struck by how the Maritime Provinces don’t have a pro hockey team. Why don’t they give a team to Halifax, instead of creating the Toronto Second Fiddles?
Shoeless:
That’s true enough, but I still think they’d like one. They just have the security of knowing they don’t need to offer billionaires sweetheart deals to land one or else they’re stuck with a white elephant.
Diceman:
Tiny, tiny population. Halifax, the largest metro in the Maritimes, has half the population of Winnipeg, the least populous metro that currently has an NHL team.
What about the Jets and Giants?
Jets are the “B” team. Seems obvious to me. YMMV.
Also, in NY it seems there’s no “cross pollination” of fandom. It goes:
Yankees/Giants/Rangers
Mets/Jets/Islanders
IOW You won’t normally find Yankee fans who are Jets fans
As this map shows, the Jets have one county in the whole country where they dominate, according to Facebook. That county would be Queens, where they used to play. Before they moved to New Jersey, they would have been the majority on Long Island as well. They are definitely the second citizens of NY.
BTW, I am Jet fan 
Even going back to before the AFL-NFL merger, the upstart AFL (Jets) was always the B league to the NFL (Giants).
Please, please, please stop this nonsense of giving team singular names.
If they put a team in Seattle, please, please, please name them the Metropolitans, after the first US team to win a Stanley Cup?
Rick-They resurrected the Senators as a nickname, so resurrecting Metropolitans seems like a good bet.
That’s exactly what they’re looking at doing, maybe in Markham (northish of Toronto centre) or Hamilton (southwest at the end of Lake Ontario). Hamilton (or somewhere in that general direction), in my opinion, would be better; a team in that heavily populated area could easily suck up fans from southwestern Ontario who can’t get to downtown Toronto.
