I'm just going to throw my two cents out there. I'd be 100% in favor of brining hockey back to Winnipeg. Crime has nothing to do with having a team in a city, look at NYC, Detroit, Los Angeles. Point proven. Secondly, the team folded because the talent wasn't there. They had decent seasons, but no great ones, not the city's fault at all. Thirdly, the arena was a bit too small. That can be fixed no problem, expansion, new building, or many other way's.
The only problem I see is that the city may not have enough people to support a franchise. Only about 500,000 live around Winnipeg, or close to that number, but compared to all of the other NHL cities, they are probably the smallest.
Toronto: 4 million
Detroit: 4 million
NYC: 16 million
Boston: 6-7 million
Chicago: 8 million
Montreal: 2 million
Compared to the Original Six hockey cities, they are ridiculously small. Then take into account the southern cities (Pheonix, Los Angeles, Tampa Bay, Nashville, Atlanta) it just got washed away.
If Winniped were a city over 1 million, I'd say put it there in an instant. But even with 500,000 people, they can still have a franchise IMO.
