Well the simplest explanation is that the league exists for its fans, not for its players.
As
@voyageur points out, it would replace an unstable team with a stable one.
And as a fan of a small market Canadian team (WPG),
you don't need to be attractive to every player in the league. You just develop them, or find the players who like what your team has to offer. Multiple players have signed long term in Winnipeg (and Edmonton, and Calgary). Ottawa has its own specific issues right now that have nothing to do with the city.
Yep, excellent point. Especially when so many hockey players, including Americans, grew up playing the game in places with winters just as bad as Edmonton or Winnipeg. And then there's all the players around the league who have families and raved about how Winnipeg was such a great place to raise kids.
My favourite story in this regard though came when the Atlanta Thrashers were sold to Winnipeg. The media descended on the few players they could find in the city and pressed them for quotes about the tragedy that was unfolding and the horrible future that awaited them. Curiously, one of them was goaltender Chris Mason.
One young woman stuck a microphone in his face and asked him how he felt about having to move to such a "frozen, wintery northern city".
Mason looked at her quizzically for a few moments and asked, "You know I'm from Red Deer, right?"
The sweet young thing nodded enthusiastically and pressed, "But the team is moving now to Winnipeg, where its very cold and dark for most of the winter." She pushed the mic closer to him.
Mason looked at her a bit longer, obviously suppressing a smile and said, "Red Deer, Alberta."
Not comprehending but aware she wasn't getting the sound bite she wanted, the reporter turned away to face the camera and began to prattle about how the Thrashers players would now be moving to the dark frozen north and would be.... etc. etc. Mason stood behind her and smirked.
They must have played that clip about a hundred times on Winnipeg television when the news of the sale broke. It still makes me chuckle when I hear people mention all the NMCs that are out there.
