I like to believe that the continued growth of the sport overseas will eventually reach a level that will have a positive impact on the game over here. The same as the enormous exposure of football overseas (soccer) has had on the game here. Obviously not to the same level as nothing will ever reach even a proportion of footballs size and ability to impact, but a positive impact that makes our highest potential 'rugby' (league and union) players simply want to play rugby as the financial and brand exposure levels would be too great to ignore. All this in a fairy tale tho.
Globalisation is Australian rugby's friend and one of the only threats to League and even worse the AFL in this country. Back to reality now... or at least back to what my boss is paying me to do.
I think post 2019 could be very interesting times for Rugby. It is projected that by 2026 there will be 20m participants worldwide which should be close to approaching the tipping point for the game internationally. Assuming they don't have to re-assess those projections as they have once already due to significant jumps in growth.
For mine, the key will be the ability of the game to develop more professional leagues over the next 10-20 years. I actually think it needs to be one of WR (World Rugby) key strategic goals. The key is creating more demand.
I know that a number of the top Spanish clubs are looking to form an Iberian League with a number of the Portugese clubs with the intent of it being professional and that post 2015 a TV network floated an offer to help establish a Pro12 like competition featuring teams from Georgia, Russia, Romania and a couple of other nations. Don't know if that's is still in play.
While PRO is likely dead in the water even if they manage a 2nd season there are a number of clubs looking to transition fairly quickly to professional entities. Those three including Canada regarding the US would be high on my priority list.
