Winston should counter sue. By the same common sense that Tom Brady must have known what was going on with inflategate, it's also common sense to deduce that Kinsman is lying to try and hit lotto. Her story changed over and over again, and has been dismissed at every level. She even had her aunt try to extort Winston for hush money.
As a parent, I look at the situation through the eyes of what would I do if my child was being framed by a gold digger looking for a payday. I know I would advise him to do exactly what Winston is doing. Pay her nothing, not one thin dime, and fight her every inch of the way. Let her legal bills skyrocket and teach others a lesson who might be tempted to play the same game.
Also as a parent, I would be appalled if my daughter used sex with celebrity athletes as a ways and means to wealth. I'm certainly doing my best as a father to teach my daughter better than that. Reinforce she's worth more than that. That she's not just a vagina cash machine. It's sad that society is still so backward and Neanderthal. In many ways, we're moving backward instead of forward in terms of our attitudes towards women and sex. We have devalued both to nothing more than a game of orgasm for dollars.
