I agree with the Idleracer. Besides the Ladies ( and APM is not on the World's team, BTW) the US team really does not have any other possible medallist(s).
Baring some unforeseen injury or a disaster, here's the breakdown:
Pairs: The US pairs are pathetic, whereas the Russian team has T&M, who should medal. P&T may get lucky too, but they should be in the top 6. States would be lucky to place somebody in the top 10 there.
Guys: Russians have Plushenko who will medal, US may get Weiss in the top 5.
Ladies: US wins here, but I would not bet on more than 2 medals.
Dance: N&K will medal, B&A may get lucky with a top 5 finish.
Total so far: US - 2 expected medals, Russia - 3 expected medals. Three beats two, doesn't it?
China could win two medals, Canada may get 2 as well. Japan may not get more than 1. Russian team does look as the strongest, even w/o Irina.
