could he do it? he has the 100 and the 200. he just split close to the world record in a relay 4x4 after running the 4x1 earlier. it looks like he could get the 400 record as soon as he wants it, or does he stick with the 1 and the 2 this year trying to lower those times even more. if he breaks the world record in the 400 in his second or third try does he then say well that was easy let me try the 800 now?
