bolt looked great. blake isthe only man who has the tools and form to beat bolt in these games.
the real battle is for bronze, assuming they make the finals it will be dix (run rounds well), gatlin (experience although i doubt he making de finals, makusha might take care of him), lemaitre, RT, carter, and frater. RT heat will be real pace.
i doubt both bledman and RT making the finals. Only one of them will get through but i hope i am wrong.
