I am amazed that they made it this long.
They didn't. They were making snide comments from the night this whole mess started. The one in particular I recall was along the lines of something to the effect that the Canadians ought to be good since they've been skating the same routine for three years. Aaaargh. I'm glad they went home. Good riddance to bad rubbish.
And BTW, I'm not so sure that they didn't know that the medal was theirs from the get-go. It would certainly explain their sloppy performance in their long program.
