It is likely all the effort for Sochi will revive Russian pairs as dominant. They have some wonderful pairs. I do not know about some province where tall skinny chinese women are grown, so to speak. So I have no opinion on the future of chinese pairs. It does seem with this great coach about to retire, there will be a dearth of 'inspiration.' It takes a great leader to do what this amazing coach accomplished in China.
They went as far as they could and it seems a good move. I personally don't see the new pairing as a great thing given his age and injuries. But, whatever. Luck to all.
