There is this twitchy little feeling out there that to be really good, skaters (and ice dancers in particular) must be changing the direction of the sport.
I don't know where that notion first came from, but I can certainly recall Peggy Fleming & Dick Button criticizing Elaine Zayak as not changing the direction of the sport. This was pretty funny, even at the time. You can't change the sport much more than to make TPTB 1. Decide to eliminate the toe walley as a separate jump. 2. Limit the number of the same triple jump in a program. Furthermore, before Elaine, a triple jump was not really required for the ladies. After Elaine, you really couldn't be taken seriously without at least one.
In ice dance, Pakhamova & Gorshkov and Torvill & Dean are always recognized as trendsetters. Some people included the Duchesnays and Bestemianova & Bukin. "Trendsetter" is treated as a higher level of excellence than just champion. Bev wants V&M to be trendsetters because she wants to assert they are on the T&D level, not the Navka Kostamarov level (for example). IMO, V&M have skated beautifully, but I am unaware of any "trends" that they have yet started.
