And Ryan Bradley did not give commentary for Four Continents, so I think we have a case of mistaken identity.
Ryan was on site as Angela Wang's coach.
For U.S. coverage, Four Continents was called by Chris Vosters (brand new to the sport, AFAIK) and Charlie White. Neither of whom was involved in calling the ladies for GPs, AFAIK.
And I find it hard to believe that the affable Charlie White would sneer at anyone.
Meanwhile, as a hypothetical scenario:
For coverage for a U.S. audience, it would not be inappropriate to mention as a positive point of interest that an athlete (who represents a different country) lives and trains in the U.S. With the positive subtext of: "American viewers, you can feel something in common with Athlete X, even though s/he represents a different country." I enjoy skaters from lotsa different countries anyway, but that type of mention might increase my attention by a notch.
