I have always heard unfavorable things about Sasha's edges, and that her spiral, though beautifully positioned, was not sustained. (I can't verify those with my own observation--that's above my skill set.) If that's an accurate evaluation, it's pretty alarming. I don't know how that compares with the abilities of other American ladies (i.e., will that weakness stand in Sasha's way as she competes at Nationals?), but I suspect that a lot of the European and Asian skaters, not to mention Joannie in Canada, are superior to Sasha in that regard.
I still love to watch Sasha skate, though. Even though there are a lot of other bendy girls these days, no one has her presentation.
