They had no choice but to throw in the towel. Things went downhill very fast when Kolyada bombed in the SP-the very first event. OTOH Canada did very well, making it impossible for OAR to recover.
I don't think that's true. Russia is only 3 points behind Canada. If Osmond, Daleman or Chan have a bad skate, that 3 points could easily be regained. Perhaps the decision has more to do with Russia's medal priorities... Would they rather have gold in the pairs or in team?
