Ice Age: Should a country’s senior nationals include figure skaters frozen out of senior – or even junior – world championships?

Over three days in late January, Alysa Liu turned into a sensation whose fame briefly reached beyond her sport.

Liu went from becoming, at age 13, the youngest senior national champion in U.S. figure skating history to appearances on TODAY and the Late Show with Jimmy Fallon, charming both viewers and the hosts.

And then, because of her age, Liu disappeared from not only the wider stage provided by those shows but also from figure skating’s stage until next season.

The situation is similar for the three young women, Anna Shcherbakova, Alexandra Trusova and Alena Kostornaia, then 14, 14 and 15, respectively, who swept the senior podium at the Russian Championships in December.
