Amongst all the threads mocking Rihanna for her poor live performances

I was just wondering what could be done to make Rihanna seem less stiff and motionless on stage.
The video for Rude Boy was on earlier and I think her tour could be improved by incorporating moves she can actually do. She looks great grinding, popping etc - so why not get her backup dancers to do the same? It'd look a hell of a lot better than whatever it is she's serving now.
