So quebec would make more than let say houston whom the city is much bigger larger metro population and bigger TV market than quebec will ever be.
Why do you keep saying much bigger? Did you make it to long division in middle school?
Pound per pound Canada is generating radically more television revenue, hockey is radically more popular, and that's if you're grouping in Minnesota/Mass/Michigan/NewYork into the picture, which has a population nearly twice Canada's population, and a somewhat comparable level of interest. The Sunbelt in comparison generates far less money, it's a very reasonable conclusion that Canadians create about 20 times the revenue per million people.
It's very very easy to argue a small town of 200,000 people in rural Canada is creating more money for the league currently, than the entire city of Houston.
With a second team it's very reasonable to think Quebec as a province might create more money for the league, than Texas/Louisana/Georgia/Virginia/Oaklahoma combined.
It isn't rocket science, you have a pie split 6 or 7 ways. And these slices of the pie are not split evenly. Hockey is very much the runt of the litter in Texas. The Dallas Cowboys alone are worth more than every southern team combined.
2-3% of the sports market in Houston may currently be the NHL. With a team that number might shoot up to 5%, maybe in 20 years, it might shoot up to 10% but that's in the scenario where the team starts winning multiple cups and hockey has gone mainstream in America. If you're waiting for hockey to go mainstream, you might as well just wait until it does and then add a team.
