Compare to men's soccer then. Quick google search (correct my numbers if off)...average MLS salary is $600k. Average premier league salary is £8.2 million.Why compare women's pro soccer and men's pro basketball?
Just an FYI, NBA attendance averages 18k and 82 games per seaon. NWSL average attendance is 11k and 26 games per season.
The point isn't the sport itself. The point is the $$$ just isn't there in women's soccer to justify the narrow focus on the pro pathway.
