After weeks of rumors, it looks like one plan to finish the NHL season has risen to the top of the list.A proposal to host games at a select few “hub cities,” possibly one per division, has continued to gain traction with the league. On Friday, NHL senior executive vice president and director of hockey operations Colin Campbell reiterated what NHL commissioner Gary Bettman stated on Wednesday night; that previous plans to host games at neutral-site arenas in places like North Dakota and New Hampshire couldn’t have worked. “We need to have an NHL arena,” he said on Sportsnet’s “Hockey Central” on Friday. “There was some talk about North Dakota and other sites. We need an NHL arena that’s game-ready, that’s all set up and ready to go for broadcasting, for NHL games. They need four dressing rooms inside those arenas to play the number of games they need to play each day. The hotels need to be adequate and what our players need.”MORE: Bettman on league return, draft: “We don’t live in a world of perfect anymore”Current front-runners are thought to include PNC Arena in Raleigh, N.C., home of the Hurricanes, and the Xcel Energy Center in St. Paul, Minn., home of the Wild. The Arizona Coyotes are also reportedly keen to host. However, Campbell said the NHL is carefully considering the available options.“There’s a number of criteria,” the long-time league executive said. “Is it a friendly hub? What state is friendly? What province is friendly? What are they dealing with [in terms of COVID-19 cases]? Obviously, you look at the New York area, it’s not very friendly, and you look at Alberta, that seems fairly friendly.”On Friday, Calgary’s mayor Naheed Nenshi announced that the city’s ban on public gatherings had been extended until Aug. 31. However, Postmedia’s Danny Austin reported that Nenshi said professional sports teams could possibly get an exemption. The extended ban comes a day after the city’s premier summer event, the Calgary Stampede, was canceled.Calgarys public events ban does include all gatherings of over 15 people.Mayor Nenshi says it’s possible that professional sports teams would get an exemption, but does not “see a world where you’re having a game at a packed McMahon Stadium this summer”— Danny Austin (@DannyAustin_9) April 24, 2020When asked if Toronto could be a potential candidate, Campbell responded positively, referencing the 2016 World Cup of Hockey held in the city. “We dealt with various practice rinks, dealt with various hotels, dealt with (Scotiabank Arena), dealt with various dressing rooms, dealt with all the issues that we’re going to have to deal with, so that’s a step up that Toronto has,” he said. “Plus it’s a 70-cent dollar, there are a number of restaurants in that square there, a number of five-star hotels within shouting distance, so Toronto has a number of excellent pluses on their side to be one of the hub centers.” The plan is far from finalized, though. NHL commissioner Gary Bettman told Sportsnet in an interview with Ron MacLean on Wednesday that the league wouldn’t be rushing back before it’s safe. “All of this is contingent, nothing has been decided,” he said. “The decision ultimately will be made by medical people and people who run governments at all different levels. We’re not going to try to do anything that flies in the face of what we’re being told is appropriate.”Regardless of where the league chooses to play the final regular-season games, it looks almost certain that fans won’t be in the stands, which would make for a strange atmosphere in the playoffs.
