Wagner was never good enough even in her prime. She has never placed top 2 at Nationals even skating her best when the U.S were even weaker than today, and it seems the U.S is perennialy down to 2 spots. This year she wouldnt have placed much or any differently even skating her best, certainly not on the podium. So no hope for her.
Zhang is even below Wagner at this point, so no hope for her either.
