I think one thing that speaks volume to Rosies knowledge on skating is in a preview for Worlds one time she said Bourne & Kraatz would have a hard time winning with all the big tricks the Chinese pairs are doing. In a preview for Canadians one time she said it should be a great battle between Sale & Pelletier and Bourne & Kraatz in the Team Event. Her knowledge of the sport is probably about on par with someone like Rob Faulds, antmanb or Dan Matheson at best, LOL!
That being said I do think she has some semi valid points, not directly rated to Chen, but that in general the quad mania has perhaps gone overboard. If you look at the difference in silver between Uno and Fernandez it is mostly that Uno got way more points for an ugly fall on a borderline underrotated quad loop than Fernandez did popping a planned quad to a still nice looking double jump after already doing 2 clean quads himself. That kind of thing is not really something I agree with. And perhaps the ISU does need to look at some revisions after this quad.
