I know quite a few of the people that put this event together. There was no shady stuff going on; those girls just brought it harder than the rest. That squad had to make it through a video tape cut and a regional competition to earn a right in the final. Every regional was recorded, so the ability to "scout" was available. Some of the audience grumbled for the same reasons some people here are grumbling - "How the hell did those white girls win a step conest?"
However they learned the skills, they showed and proved.
Edit: Just asked my people - and based on how tight the final scoring was between the first and second place teams (and the controversy of the white girls winning IMO), the first and second place squads have now been deemed "co-winner" due to a "scoring error"
Everyone happy now????
