As far as Evan's achievements, he was close to the top before his last Olympics, and he won the 2005 Worlds before winning the 2006 Olympic Gold Medal (OGM). His accomplishments were the results of trying hard, believing in himself and getting good coaching. He belongs up there with many other World & Olympic Champions.
Although, Evan is tall, has a great body and is handsome, and he got some nice corporate endorsements (Ralph Lauren, Coke, AT&T),
experts rated his overall endorsement prospects as "fair". Because of his look, I think he could play a "James Bond" or "Mysterious Stranger" type in tv or print ads. If he doesn't talk too much in the ads, he is still believable. Evan's agents didn't seem to find a way to shore up Evan's personality to increase his marketability. I think that they wanted to turn him into something that he wasn't. And when they couldn't mold him into something else, the management team just let it go.
In contrast to Evan, Nancy was very well-packaged by the Scotvolds to look like an ice princess, in contrast to her working class upbringing. She even fixed her teeth! Nancy didn't even win the gold, and she still got a $10 million Disney deal in addition to other endorsements. I also noticed that Nancy seems carefully rehearsed and coached for on-camera interviews. In situations where she is not coached, her "real" unpackaged, working-class personality comes out. She also ended up marrying her agent, Jerry Solomon. There was a scandal attached to that since he was recently separated from his wife and family right around the time he started to date Nancy.
However, IMHO, other skaters like Scott Hamilton, Brian Boitano (both OGM winners) or even Johnny Weir (no Olympic medal) seem to stay in the public eye because of their personalities. Scott is bubbly and talkative during interviews and commentary. Brian Boitano can do cooking and HGTV shows. There is a South Park showtune written about him, "What Would Brian Boitano Do". Johnny gets to be himself on NBC Sports with his fashion forward outfits and colorful sports commentary.
It's somewhat surprising how little love & appreciation he gets for skater of his calibre. Is that Olympic Gold in Vancouver that made him unlikeable for people after beating favoured Plushenko without quad or was he just "boring"? Or does his personality / public image mattered? What do you thought / think about him, do you like / dislike or you are just indifferent towards his person and his skating? It seems he's not an idol for anyone unlike other famous retired skaters like Lambiel, Joubert, Takahashi or even Buttle.
