There may be something to that. The 7 Canadian NHL teams are more or less guaranteed cash cows for the league. Even without winning recent championships, the teams are generally seen as consistently profitable. And hence are not a priority for the head honchos of the league overall. Whereas newer teams like Las Vegas Golden Knights were seemingly treated as a pet project where they need to be successful right away to carve out a winning fan culture. Along the lines of a Tampa Bay Lightning where they've excelled despite being in a place that traditionally isn't a hockey hub, apart from snow birds from Canada and northern US. If the Golden Knights slump right away then they'd risk being mired in mediocrity or worse in irrelevance like the Coyotes, and the Atlanta Thrashers before they moved to Winnipeg.
