We've done it ourselves.
It's really hard to do actally. Take a look at our list and then post yours here.
PS. Here is our top 5 to get you in the mood.
Up to 30% (Up to 1 out of 3?)
1. Galen Rupp - He has two chances to medal and in the 10,000, the Kenyan and Ethiopians squads aren't very credentialed at all on the track in the 10,000. Only one Kenyan, Moses Masai, and one Ethiopian, Kenenisa Bekele, in the 10,000 has ever medalled before outdoors and both of those guys don't seem to be in their prime. To be truthful, he is the only American born athlete (maybe Lagat as well) we can really imagine wining gold. While we say he has two chances to medal, can anyone really see him doing it in the 5,000 if he doesn't first medal in the 10,000?
2. Evan Jager - On paper, it looks like there are at most five guys who should beat him if everyone has a great day. If one of the Kenyan falters, watch out and Kemboi was recently in prison.
Up to 25% (Up to 1 in 4?)
3. Bernard Lagat - This may seem low for him but the competition is very, very tough as the Ethiopians are young and very good, plus there is Farah and a few Kenyans. Didn't medal in 2008 at age 33. Hard to see it happening at 37.
4. Nick Symmonds - Making the final is tough but once he's there he's got a decent shot.
Up to 15% (1 in 7?)
5. Morgan Uceny -Despite being world #1, it's hard to see her medalling 1 out of 5 times as 11 women have broken 4:00 this year. Let's hope the drug testers are good and then her odds go way up. On fitness, Flanagan might deserve to be the top US women's hope but falls are way more often in the 1,500 and could benefit Uceny here. Afterall, she got screwed by a fall last year.
