Their presence here in the United States has delivered a powerful boost for the game which has ambitions to grow in a nation where sport is dominant.The people who run rugby in the USA were delighted when the Wales visit to the Chicago Bears which attracted stateside publicity which got folks talking.
A visit to a baseball game in Chicago also raised a metaphorical flag for rugby when images of the Welsh players in the crowd popped up on the big screen.
Team manager Alan Phillips insists that all public appearances take place with the squad in co-ordinated Under Armour gear so there is no mistaking who they are.
The citizens of Chicago are friendly folk and there have been numerous occasions when the sight of a group of athletic looking Welshmen in matching sports gear strolling down the sidewalk has attracted a question or two.
When the match takes place it will be transmitted live on television in the USA so hundreds of thousands of new pairs of eyes will be watching.
Those are the some of the reasons that the rugby administrators in the USA are so pleased to have the Welsh squad here as ambassadors for our sport. Over the past six years there has been strong growth in the number of people playing rugby in the USA but the sport has a long way to go against the dominance of American football, baseball and ice hockey.
The new USA Head Coach Eddie OSullivan acknowledges that he faces a huge task and is following the Argentina model in his bid to get more of his players into the professional game.
That means those with the talent and ambition to make it at international level will be encouraged to play professionally abroad.
That is already happening with some of the current USA squad which means that their international team can prove tough opponents.
His long term aim will be to oversee home grown professional leagues in the USA but he concedes that is very much an ambition for the future.
Right now he says his focus is on a good show against Wales which will be ideal preparation for the Churchill Cup and then his priority of getting qualification for the next Rugby World Cup.
Meanwhile the Welsh team are already focused on a big performance on Saturday with the important Thursday training session proving an intense and physical workout.
Robyn McBryde says he is pleased with the development of this squad and particularly happy that some new young players have stepped up.
He has told his players that the USA will pose a physical threat for a full eighty minutes of play so there will be no hiding place on Saturday.
The on the field training has been balanced with hours of analysis and planning for individuals and groups of players so everyone knows exactly what is expected of them.
The Welsh players have already visited the stadium, strolled through the changing rooms and walked the pitch.
Now they are ready.
