Not sure why they are so disappointed. They had no Pairs or Ice Dancing team that could contend with the other teams. Even Italy was stronger across the board with the exception with the Men's.
It's the reporter who is disappointed.
when in doubt, blame the reeds
Their ice dance and pairs teams are extremely weak, so they should be happy that they made it to the finals. By the next Olympics they can work on developing skaters in all the disciplines, and I am sure they will be motivated to.
