London: All anyone's talking about ahead of the men's 100 meters is the showdown between Olympic champion Usain Bolt and world champion Yohan Blake, a pair of Jamaicans who train together.
As the premier track and field event of the London Games gets started with opening heats Saturday, it seems everyone has an opinion about who's going to win - and the answers tend to be Bolt or Blake.
There are other contenders. There's the third Jamaican in the field, Asafa Powell. There's U.S.-record holder Tyson Gay, surgically repaired hip and all. And there even is another past Olympic champion, Justin Gatlin of the U.S., who walked off the stage in Athens four years ago with the 100 gold.
