Ashley fell twice at 2013 Nationals and didn't volunteer herself off the top of the podium. Mao didn't hand her gold medal to Suzuki at NHK. Nor did Pdiddy concede the win to Denis Ten. Sorry, but skaters aren't all that altruistic.
I'll go for Wagner, Gold, and Nagasu, as long as they are all uninjured and are skating well next season. Much as I hate to admit it, I still prefer watching Nagasu on a bad day vs Zawadski, Zhang, Flatt, etc. on their good days. Gao is a nice skater but skates too intellectual for my taste, she's just missing the "it" factor and therefore has limited upside....also limited downside. Czisny is done for health reasons alone--I don't think we'll see her back except for a few halting tries at competitions in the fall. Unless something miraculous happens, I don't think the Hicks, Miller, Wang, etc. contingent are going to be able to pull it up to where they need to be...try for 2018 ladies, when you will all still be young yet more seasoned.
It depends on the purpose of that third spot. Why did US want that third spot? Was it because they want third US lady to be an Olympic medalist? Or did they want to give younger skaters a chance to experience Olympics?
I think Ashley and Gracie would be going as long as they don't have a meltdown at Nationals next year. And any lady from Top 10 this year can be third US lady, and I'm fine with that unless really inconsistent skater ends up being a third lady.
