Alysa hasn't done one in competition either. (And, if I'm reading the article correctly, is only doing them in practice with the harness.)
If we are comparing like to like, there are probably a dozen female skaters working on quads just like Alysa is.
Eh, yes and no. Caro was hyped but when Mirai beat her for the Junior title, then they were both hyped.
But I don't think anyone was projecting either of them to be "the next Kwan."
Where to begin, where to begin....
1) Technique.... People said Mirai would be the one who would get through puberty unscathed because her technique was better than Caro's. That isn't exactly how it happened.
2) Hype: Ashley Wagnor was never hyped from the beginning. She wasn't hyped at all until much later in her career. And she certain wasn't part of the Caro and Mirai are the future hype. Ting and Hanna are still being hyped and Hanna has excellent technique and Ting's isn't bad so the statement "but the difference is in the technique and how the hype just centers around Alysa" is off-base at best.
3) US skaters don't lack drive. Competitive nerves maybe. But they are driven.
4) The US has been a power in ice dance for ages now and the men are nothing to sneeze at. This idea that US skating rises and falls on the Ladies team is out-dated.
