I don't think it would be wrong to send Karen to the Olympics, but it makes me sad because I think Karen, even if she may have the potential of scoring higher than Ashley at the Olympics, is a less unique skater overall. Ashley may not have the consistency or confidence she had in prior seasons, but she still tells a story on the ice like literally nobody else in the world. She is always exciting to watch, whether she does well or poorly. I don't think she should go to the Olympics purely because of this quality, but it is extremely sad to see someone like her miss out by so close a margin. Add in the fact that she played such an important role in the U.S. having 3 spots the past six years, and in getting 3 spots back after Alissa Czisny, Emily Hughes, Rachael Flatt, and yes Mirai Nagasu lost them in 2009-2012, and it is extra sad. This could possibly be the last competition of Ashley's career, and IMO is not an appropriate bookend for her.
It it were up to me, which obviously it is not, I would send Ashley to the Olympics, on the theory that her PCS were underscored and she would have been in third place if given her typical international scores. That way Ashley gets her swan song (and she always skates best when she feels she is the underdog). Karen is very unlikely to win an Olympic medal even if she skates perfectly, and the U.S. needs her to have the motivation to stick around for another quad and to fix her serious underrotation issues. I would send her to Worlds.
Like I said though, I don't think it would be wrong, and may even be more appropriate, to send Karen to Olympics. (Ashley's anger also is not a great look - she should let Rafael do the yelling.)
In contrast, I am beyond happy for Mirai. Although I don't think she has been scored unfairly over the past several years, and I still do not think she is a great performer or has the transitions or skating skills to be a leader internationally, she has clearly put in so much work to change the judges' opinions and get them to reevaluate their dismissal of her as a medal challenger. It is so inspiring to see that kind of effort and drive pay off, and I am so happy that she not only will be going, but that there is absolutely no question that she's going and deserves to go (unlike last time).
With respect to Bradie, I don't believe that her level of consistency has been seen in the U.S. since Michelle Kwan. And while she is no Ashley in the performance department, she is at least as good a performer as Mirai on a normal day and not significantly worse than Karen or the other U.S. skaters, who are all pretty stone-faced and average. Her landings are larger, more rock solid, and have better flow than even many Russians, and I think people are being premature when they say she has no chance of getting high PCS in Skating Skills and Transitions, at least, from international judges. She got surprisingly good scores from international judges in her first senior international GP this year despite nobody having heard of her and her not being on the USFSA radar whatsoever, so I think the international community is not opposed to scoring her as a threat.
While I do think Ashley was underscored in PCS (it makes no sense to score her less than the international panels do), I think the person most underscored this nationals was Mariah.
Starr is great and I look forward to seeing what happens with her in the next quad. I hope she isn't discouraged that she had such good skates and still placed relatively low. I hope she is sent to and does well at junior worlds. I also think they should send her to FCC.
ETA: didn't realize they had already announced the Olympic, World, and FCC teams when I posted this. I am fine with the decision, although sad for Ashley.
