While it was exciting for a while, but now I'm becoming suspicious. Japan cannot become a sprint power overnight unless they are doing something strange. Where did all of these guys come from? I would say the same thing if all of a sudden Ireland became a sprinting power within a year or two. I know Japan has always had some talent, but nothing even remotely close to this. Too many guys running world class times from out or now where. I hope I'm wrong but usually where there is smoke there is fire!
