More exposure for women's hockey is great!
When a league exists that supports its athletes as professionals, other active women's hockey leagues won't cease to exist, nor should they.
There is potential for growth while others, like the @PWHPA, fight for more.

Men do not only have the NHL to aspire to. Countless other leagues exist for them to continue playing the game they love, but the best of the best have a league to play in where they're treated as such.
This is possible for women's hockey too.

Just because something exists, does not mean it should be the only option.
There is room for more, there is room for better.
The @PWHPA isn't fighting to be the only option, they're fighting for women and girls to have better options.
