They were all so American. I remember them at the Nationals.
The original question didn't limit the discussion to Americans -- you did in a later post. But it's amusing that after your rolleyes at me, you promptly brought in a non-American yourself.
You left out Sonia Henie and her partners, .
Whatever. In response to the original question, I think that if anything has happened to pairs, it's pretty much what's happened to singles, too -- whatever gets the levels/points is what is concentrated on, and that is no longer being clean or (in the case of pairs) staying synchronized, or having the big jumps, etc.
