There’s something remarkable about the opening scene of Copa 71. Brandi Chastain, hero of the winning American team of the 1991 Women’s World Cup, is given a tablet and shown footage of the 1971 Copa tournament, a massive women’s soccer competition in Mexico City two decades earlier than the first official FIFA Women’s World Cup. She had no idea it even existed. I suspect many other diehard women’s sports fans didn’t either (I certainly didn’t).
