OTOH the Jets never should have left Winnipeg in the first place. I’m not even a hardcore NHL fan, but had some work to do that was impacted by the Jets’ move to Phoenix... It was an eyebrow-raiser to be sure! One city is cold, an obvious fit for the NHL... The other is blazingly hot. “One of these things is not like the other, one of these things does not belong...”
If hockey was played outdoors you’d have a point but indoor arenas make the weather a moot point (hence why there’s hockey in Vancouver).
The real problem I see with retrenching to Canada has nothing to do with climate. It’s the deepening demographic winter. The northern tier countries that breed hockey players are getting old and sterile. The same can be said for the northern tier US. My area of Pennsylvania is churning out hockey instead of football players now. That will help but there are many fewer kids here than there were 30 years ago.
