I think that these interviews should be taken with a grain of salt. After a big disappointment, people will say anything to try to soften the blow in the short term, or to get people off their back.
All that having been said, one thing I noticed in Symmond's interview on Flotrack was a lack of a winner's mindset. He was in the chase for podium, not in the chase for the win. Psychologically, I think this is huge, and probably a big difference between many Americans and third-world athletes. I think that he never have a shot at podium if he wasn't trying to beat Rudisha. Yes, its an easy thing to say, and Rudisha is the world record holder, but I think that both Kaki and Borza were unafraid to go after it. Tyson Gay also comes to mind as an example of what can happen when you are shooting for the top. Gay has said before that he tries to have the mentality of a 9.5 runner, because he knows that is the only way to beat Bolt. Like Bolt, Rudisha is in a class of his own. But also like Bolt, Rudisha is beatable, as Tyson Gay has proven.
