Here's a quick assessment of men's running favorites IMO ... the "grade" after their name indicates the degree to which they are a favorite, with "A" being a "sure thing" and "C" being the most modest favorite (almost anyone's race).
100: Monty, C+ ... He has the edge, but Mo Greene, Gatlin and others have almost as good a chance in a race where surprises could easily happen. Too early to know form of most of these guys.
200: Kederis, C+ .... Though the Greek has won 3 biggies the last 3 years, still fairly wide open, with Americans like Gatlin, Capel in the mix.
400: Second big 400 of post-MJ era is totally wide open in my opinion ... no favorite (and will anyone even approach sub-44?)
800: Yuri B., B- ... The B's, David K. and Wilson K. all have a solid chance, but look for the Russian to win his first major.
1500: El G, B+ ... has obviously had better luck in WCs than OGs ... not the 3:26 El G, probably, but no one ready to surpass him.
Steeple: Cherono, B- ... Who will be the Kenyan star this year? With Boulami out of the picture, the other sub-8s are the best bets.
5000: Bekele, C ... He doesn't have the track creds yet, but the event has no dominant runners, just a bunch of guys who can run sub-13.
10000: Geb, B ... Geb will still be the fave over Bekele or anyone else, but the Ethiopian great is fragile and coming off the 2001 loss. Not the heavy fave he once was.
