Nathan had a bad skate. Stuff happens.
I think that Nathan has as good a chance as any of the other contenders at skating clean-ish at the Olympics. I think he has the same chance as the others of succumbing to nerves, or not. If Chen skates OK and delivers his technical content, I think that Hanyu is the only one who is clearly favored over Chen. That's provided Hanyu skates well, too.
Points, points, points. Six quads get a lot of them. I can easily see Nathan settling into that ol' quad groove and hitting everything.
Hanyu
Chen
Jin (or Uno) (sentimental choice)
Uno (or Jin)
Fernandez
Chan (I think Patrick might over-reach on the tech and not deliver his best performance as a result. I hope I'm wrong.)
Kolyada? (same)
That's my story and I'm sticking to it.
