I see Carolina as the dark horse. Earlier I thought she was an OGM contender. Now that seems difficult, but a silver or bronze is within her reach. She was clearly rusty at the Euros, having dealt with an injury recently. I think in the Olympics she will look much stronger. She will need all her jumps though to win the medal. The field is very competitive, with experienced and younger skaters.
Carolina is always way over-scored IMO. I don't get her appeal other than her amazing speed and flow across the ice. She buckles under pressure and doesn't have the technical ability of the others in the field. I like her skating because she is unique (tall, gangly) but I just don't think her skating is worthy of an Olympic or World Medal. It's just my opinion.
