I guess personally, I'm over Sasha. Does she have the right to try for a comeback, sure. Do I think it's fair - it's not my decision. Do I personally wish she wouldn't complicate an already difficult decision between Nagasu, Flatt and Wagner (my top 3 at least), yes.
I guess I feel she had her time and it's time for others to have the olympic experience. For me, it's not about placement so much as it is about allowing them the experience of being an olympian.
