WNBA players make, at most, 22.8 percent of revenue from their league. NBA players make between 49 and 51 percent of league revenue. 

The WNBA brought in at least $51.5 million last year and that number could be even higher, which would drop the players' cut to an even lower percentage.

A WNBA player's maximum salary is $115,000 for those who have been in the league six years, entry-level NBA referees earn $150,000. The average salary for WNBA players is around $79,000.

"I don't know how much traction we're really getting with these conversations," said Wings guard Skylar Diggins-Smith, who has been a vocal advocate for equal pay for women in basketball. "They may be coming up and causing conversations but what's actually happening [to change], I don't know the numbers."

The WNBPA can opt out of their current collective bargaining agreement after the 2019 season.
