The two-time defending Olympic champion Brazil women are chasing a golden three-peat on home soil this summer. The top-ranked Americans are seeking redemption in Rio and their first gold ever.
This is the rivalry to watch in the women's volleyball tournament.
The Americans expected to win gold four years ago in London and instead were stunned by the Brazilians, who captured their second straight Olympic title.
Now, the Brazilian women have home court, so beating them in Rio would be even more monumental.
And coach Karch Kiraly's close-knit U.S. squad believes it has built the right mix to challenge for the top spot on the podium this August in Rio de Janeiro.
