Do the English ever wonder why the Kangaroos are dominant while the Wallabies struggle?
They don't see the Kangaroos. They do see the Wallabies pretty much every NH autumn.
As previously mentioned, some think the Kangaroos ARE the Wallabies.
Should the ARLC send representatives to England to dispel these myths?
They could appear on English TV shows to point out that the NRL draws more money from broadcast rights and higher attendances than any other club "rugby" competition on Earth. Show them the value of Origin to the broadcasters and Australian public. It might get a few people interested in watching the competition.
I've always thought NRL has a better chance of gaining traction in the South of England than SL. All manner of convoluted reasons for that assessment.
This is why I didn't completely pour cold water on your proposal that the Dragons could grow an English fanbase (although forget changing the moniker to Lions, tradition would be central to any allure the club might have).
The NRL would have to see it as a long-term punt. There's no way they'd make money short-medium term.
It would have to be this way round. NRL partners with a sympathetic FTA broadcaster to build awareness of the game and comp. On the back of that, individual clubs market their brands. Some would have more potential than others.
Might be hard for Aussies to understand, but if I were picking a NRL franchise likely to be the most attractive it would be the Warriors.
