The thing about skating is, just as the cliche goes: the ice is slippery. Kevin Aymoz is most certainly a top skater and he failed to qualify for the free skate at Europeans last year, forget Worlds. Skaters like Kiira Korpi, Sarah Meier, and Nobunari Oda have had disastrous performances at Worlds that didn't even get them into the final rounds. There's always a chance of skaters who completely fall apart at the Olympics, as top contenders, and find themselves outside the top 10-- think Brian Joubert in 2010. Just like... oh I don't know... every other sport there is, things happen and people have bad days. Champion golfers miss the cut in big tournaments all the time. Top tennis seeds sometimes are out in the first round. Top gymnasts have a bad performance early in the week and then don't make the individual all-around. There are favorites in every single sport, and there are dark horses. It doesn't mean the favorites are always going to win, let alone be in the top positions.
ISU Majors have never, ever been a 'pro versus am' or 'legends versus newbies' or whatever type of setup. It's a group of international skaters, who since the inclusion of minimum technical scores, have had to achieve some kind of level of mastery to even get into these events. I can't mind-read, but I'd guess the Professional sport distinction is one that determines it's not some club sport or leisure thing. Anything in the Olympics and people are going to try to argue it's not pro? Well, okay.
And you know what? All three of Igor Reznichenko's Europeans placements were better than what Aymoz did last season-- even if by only one spot or two.
