Women's sports will always be below men so I guess that since NORMAL clothed female tennis players weren't selling a single seat in a tournament maybe they changed their clothing to the mini skirt and I suppose that started to bring a couple of men/women to their tennis matches. Then they started adding the grunts and moans when they hit the ball and people got a little bit more into it or something.....I am just speculating .

Maybe if WNBA players wore mini skirts and grunted/moaned when throwing a pass or dribbling the ball, maaaaaybe they would be able to fill an arena at least half way .
