Teams in markets with fewer than 300,000 hockey fans, however, have tended to lose money, and that’s where the wisdom of adding franchises in Seattle and (especially) Las Vegas gets iffy. We estimated that Seattle contains about 240,000 NHL fans — fewer than that of Phoenix and Florida’s Tampa Bay, home to two franchises that have struggled to turn a profit for many years. And if Seattle is an enigmatic choice by this metric, Las Vegas would be a disaster. According to our estimates, there are only 91,000 hockey fans in the Vegas media market, which is nearly 40 percent fewer than even Nashville, Tennessee, the least-avid current NHL city, has.

And it isn’t as though the NHL was lacking for other options. Our research showed that, in addition to Quebec City and a second Toronto franchise, the Canadian cities of Kingston, Halifax and perhaps even Moncton, Sherbrooke or Sudbury could each reasonably hope to support a team. From the standpoint of fan avidity, all were more attractive markets than Seattle — not to mention Las Vegas, which was sandwiched between Milwaukee and Kansas City, Missouri, as the least hockey-mad of the potential expansion sites we examined. Each of those seven Canadian municipalities also contained more NHL fans than five current NHL cities: Phoenix; Columbus, Ohio; Raleigh-Durham, North Carolina; Miami and Nashville.

Here's an image from a previous article referred to in this one talking about number of fans:
