It's kind of tough. I coach U18AAA girls hockey in Canada; We have a couple girls that have already committed to a few colleges, we have a few 14 year olds playing up that have committed to junior programs, and even our lower-end girls that are aging out are atleast trying to go play ACHA D2 or D1 somewhere. Not a single one of these girls ever talks about any women in the PWHL, or that play the game at a higher level except girls they played with, girls that played in OUR organization and moved on to be good players in the NCAA or nationally or girls from the area playing for Canada.
These girls care way more about having the same tape jobs and playing like Bedard and Easton Cowan and Zegras way more than anyone in the PWHL, NCAA, women's national team, etc...
They're good hockey players and know and love the game; they are aware that the men's game is played at a different level, they are humble about how they get worked by minor midget AA and AAA boys in summer skates. They've also seen half a dozen women's pro leagues come and go in the last 8 years and I'm sure to them this is probably just another one to toss on the pile.
I hope that the league does well, and that it finds its audience that allows it to sustain itself independently to give women a place to go actually have a professional career and a goal to work for like boys have with the NHL that won't disappear in a season or 2.
The challenge is creating long term interest and being able to get people to pay enough at the gate consistently to not make it a black hole investment. Around here, you can drive 15 minutes in any direction and watch a Jr B game that is played at a much higher level than the PWHL for less money. Drive 45 and you can find a Tier 2 Jr A game and in most big centers you can find an OHL game for the same price or less, minor midget AAA or a bar to watch the NHL. It's a tough sell to create repeat fans.
I will watch games if girls I've coached ever get games in the PWHL to support them, but unfortunately have popped on a game here or there on youtube to see how it looks, and I can't say I'll be prioritizing watching it over anything else.
Edit: tier 2 jr A, not tier 2 AA
