As overpowering as the US team of NBA stars looked in routing China to open their Rio Olympics run, the frightening part for rivals is they have plenty of room for improvement. "I know it's easier said than done, but for us to come out here and win by 60 and still can be better, that makes it scary," said Carmelo Anthony, seeking a men's basketball record third Olympic gold medal. Venezuela, which has no NBA players, has fought the closest of any team against the US squad since it assembled three weeks ago, losing 80-45 in Chicago on July 29.
