Here's what I don't get the whole IMG-JSF angle of this affair: I have no idea why people would think that Yu-Na would be particularly offended/shocked by Brian's close relationship with IMG. Brian Orser has been an IMG client for years, long before Yu-Na came to be his student (and if I recall correctly, he's been with IMG even before Yu-Na was born). Long business relationships like that tend to create close ties, and surely Yu-Na would have left Brian long ago if Brian's close ties with IMG are the issue here. Plus, is Brian's having both Yu-Na's and IMG's interests at heart truly mutually exclusive? I doubt the entire IMG is out to get Yu-Na--her team's beef is with IMG Korea, IIRC.
And about the JSF thing....well, there have been groups of Japanese junior skaters, as well as other skaters from many different countries, training at the Cricket Club every summer long before Yu-Na was a member of the Club. Surely Yu-Na would have, again, left the Cricket Club long before if she was truly uncomfortable with the presence of some Japanese junior skaters who in no way pose any threat to her competitively. And all this talk about Brian's interests being more in line with the JSF's--are they anyways? He pretty much clearly indicated that he has no interest in coaching Mao Asada, the pride and joy of the JSF, and besides, what's wrong with Brian working with Japanese skaters who pose no direct threat to Yu-Na (e.g. someone like Yukiko Fujisawa or Nobunari Oda, etc)? Is Brian supposed to have absolutely zero contact with all Japanese skaters based on their ethnicity simply because Yu-Na is his pupil? It's not even like Brian has declared himself the new Nikolai Morozov, circa 2008. All this talk about Brian working with the JSF appears to be hearsay, anyways...is Brian even directly working with any Japanese skaters right now?
