By Steve Keating RIO DE JANEIRO (Reuters) - For every athlete who wins a gold medal at the Rio Olympics it will be a big deal. For the United States women's basketball team the big deal will be if they do not. The U.S. women's team are one of the great Olympic dynasties, going for a sixth consecutive gold medal and riding a 41-0 unbeaten run that stretches back to the 1992 Games in Barcelona.
