I admit to having mixed feelings about the legacy of Irina Rodnina and her partners. Obviously her competitive record speaks for itself. But she took pairs skating in a different direction. Instead of "two skating as one" the discipline became "huge tricks." The "gorilla and flea" model was not far behind. It is interesting to me that the popularity of ice dance began to increase at about the same time that the allure of pairs skating diminished, at least in North America.

Here are Rodnina and Zaitzev at the 1976 Olympics.
