WELLINGTON, New Zealand — It’s rare for the New Zealand All Blacks to slip under the radar anywhere, but they will find themselves in unfamiliar territory in Chicago this weekend. But in a country where the N.F.L. dominates, the average American won’t know much about the world’s most successful rugby team.

The All Blacks, the current world champions and world No.1, hope that will change by the time their sold-out test match with the USA Eagles kicks off Saturday at Soldier Field, the home of the Chicago Bears.

Rugby is growing in the United States thanks largely to the inclusion of sevens rugby (the shorter, faster, less complicated version of the game) at the 2016 Olympic Games in Rio de Janeiro, and the possibility of grabbing a medal has opened up funding for the sport.

The American team is one of the core teams in the HSBC World Sevens Series and finished 13th last season. The top four teams at the end of this season, which began in Australia in October, will automatically qualify for the Rio Games.
