Hmmm, you mean teenybopper tech potential in the current quad-crazy Russian teenybopper phenom environment?
I disagree with your broad statement. Alysa has talent that is surely worth nurturing and investing in, but so have a lot of other U.S. ladies possessed high level competitive talent over the years, despite the unusual Worlds and Olympics podium drought for U.S. ladies (broken a bit by Ashley Wagner's silver at 2016 Worlds in the United States).
Since the Sasha/ Michelle era, the talent among U.S. ladies has been nothing to sneeze at. Mirai Nagasu is the first U.S. lady to complete a triple axel at the Olympics. Mirai possessed superb all-around talent despite experiencing challenging personal obstacles and institutional opposition which she overcame to achieve significant personal victories. Ashley Wagner was a gritty overachiever who kept U.S. ladies in the hunt, and she ultimately is the one who broke the World podium drought when it was supposed to have been Gracie Gold. No one should ever discount Gracie's enormous talent and huge potential. Simply because what was anticipated and expected of her did not fully materialize, should not be a cause for head-shaking gloom and dismissing what she was able to accomplish. In fact, Gracie's story should be a cautionary tale for U.S. figure skating and her talent should never be dismissed as a footnote in the annals of U.S. ladies figure skating.
The talent and potential that has abounded among U.S. ladies continues: Polina Edmunds, Karen Chen, Bradie Tennell, Mariah Bell, et al. By now figure skating fans should realize that talent and potential aren't enough in any case. It's about luck, timing, and politics, amidst a multitude of unpredictable factors. The bottom line is that talent in the rest of the world has increased and deepened. As well, luck, timing and politics too often has not been in U.S. ladies' favor over the past 24 years.
Alysa Liu coming onto the scene has been beneficial for all U.S. ladies in the sense that the more talent and potential that exists helps push everyone to improve and to up their game.
