I don't know what to say, but I can't disagree with you. It's not that the rest of the world has passed us by. If we had skaters who were merely competent but largely reliable, then we could say that. But so many of our top-ranked singles skaters (some with real talent) seem to crumble like a sugar sculpture in a rainstorm. I do wish Davis/White would get more prominence, because they're stunning representatives of American sport. But I also wish we could find someone with a bit of drive and calm who was also good at singles skating.
Really, instead of having Yuka Sato attempt to coach American skaters, she should just come back as a competitive skater and skate for the U.S. She's married to an American, after all. Maybe she has a U.S. passport by now.
