This game is looking like the biggest thing to happen in the League world in decades.
Games in America in the past have been wasted efforts because there has been no way to follow up on any interest generated in the sport - but a big game in NY at this time will be different because there are already 8 teams playing in the New England region, so infrastructure is in place before the interest is created.
The estimate is that there are 20,000 ex-pat aussies in NY, and probably that many pommies from the League playing areas as well. There are also roughly 10,000 Rugby Union supporters in the New England region, and American Union supporters are not strongly anti League. If the game is marketed to them they will go and have a look at the best Rugby team to play in their region (either code).
The Americans are working hard at getting together a squad who won't be disgraced, so the game will end up being a great showcase of our sport at one of the most famous venues in the world.
