Some quick history 
“The U.S. and New Zealand teams have met on only three occasions and New Zealand has won each time: 51-3 in 1913 at Berkeley, California - 11 years before the United States became the last Olympic champions - 53-6 at San Diego in 1980 and 46-6 during the pool stages of the 1991 World Cup.”
Good luck to your boys!
