I will direct you to this column from the Winnipeg Free Press. The author, Randy Turner, is admittedly bitter about Winnipeg losing their team and the NHL's practice of moving into "non-traditional" markets in the US, and his tone is off-putting. But here is the relevant passage from the column:
...it's obvious to anyone listening to what you can't hear that the NHL's Great American Experiment is dead. Do you notice that no one ever mentions Kansas City or Las Vegas as possible relocation sites anymore? Just a few months ago, all you ever heard was that those two cities were one-two on the NHL's list. Now? Not a peep. And Kansas City is still sitting there with a brand-new arena, dying for a team.
And you're more likely to read a story about Quebec City's preparation to return to the NHL than Las Vegas.
Of course, putting teams in Las Vegas or Kansas City was a pipe dream to begin with, but that never stopped the league from floating the idea or pundits from repeating the possibility, without taking into account the millions of dollars flushed down the toilet in places like Tampa, Phoenix, Nashville and Atlanta.
I really haven't noticed a drop-off in rumors about KC. I still see "peeps" on my "Kansas City NHL" Google news alert. But all the smoke with no fire is getting old.
