I don't have a horse in the game because I hate pro sports. But both sides are stupid. Why would these bimbos take a job if they didn't think it paid enough? And why would the teams expect these girls to follow them around the country for free, or even lose money if they have to buy their own costumes?
I actually have seen this behavior in action though, so I'm aware how stupid some people are. My second wife was a "dancer" for a couple years after I met her. Tommy Lee was in town for a show and came into the club. He asked my then-girlfriend if she would dance for him, she said sure and asked for the money. "No," he said, "I meant for free." She told him to keep looking. Over the course of the night the older, wiser dancers stayed away from him but the stupid young chicks were all over him, dancing for free. I would guess most of these cheerleaders are in the second category, they want the attention and are happy to do it for free.
(Yeah, yeah, in before the "Sorry dude your wife banged Tommy" comments.

)
I think the teams will cave, because they will be able to pay these girls a pittance and still remain legal. But it's still a stupid fight.
