How many sports fans in North America would watch the SHL if they had all the best Swedish players, or even the best players in the world for that matter? Hardly anyone at all, maybe a few hockey hipsters as an extremely small-time version of the North American EPL fans. Just like the overwhelming majority doesn't give a damn about how the NPB compares to the MLB. If an Ohtani comes over and makes it big then and only then they may take interest in that individual. If he stays in Sapporo then absolutely no one will care about him even if by some objective metric he's the best player in the world.Come on, you know fans would rather see better players play in better leagues. If you can't tell the significant talent and quality difference between SHL and NHL games then you are a casual fan at best.
And yes, while the NHL has expanded into new regions. Same market revenue is up consistently over time.
Expansion and moving teams to more viable markets is ONE reason for revenue growth, what is your point?
