What kind of question is this? Of course I want hockey to be more popular. You would have to be foolish not to:
1) More money to the players. To me, its absurd that Connor McDavid, a guy that is the Patrick Mahomes of the NHL makes as much as some #2 WRs (looking at you Sammy Watkins). I'd want NHL players to be compensated more for what they do, especially relative to the other pro sports.
2) Providing different perspectives to the sport. You can't complain that hockey is an "old boys club" or "lacks innovation", yet want the sport to not be more popular. A good part of popularity is that different people begin to look/analyze the sport and find unique solutions/strategies. Just as an example, look at the innovations made in pro football as people from different demographics began to enter the sport.
3) More scrutiny on people that deserve it. I feel like there's so much incompetence that gets a pass because hockey isn't as popular in America and Canadian media isn't as critical. I feel like with more exposure, Eugene Melnyk would be villified like James Dolan or Jason Botterill would be looked at like Ryan Grigson.
4) Bettman and Co. would stop trying to change hockey all the time. Hockey is the only "major sport" that fundamentally changes itself during overtime. Where every other sport keeps things the same, we literally change it from 5v5 to 3v3 then to 1v1. Why? because Bettman and Co felt it would be more popular. The stupid divisional rules we have now for seeding? Why? Attempted forcing of rivalries for popularity. If hockey was more popular, there wouldn't be this need to constantly change everything.
