In marketing the game the ARU should focus on rugby's points of difference.
What's different about rugby? Values/culture (particularly things like respect for officials), game for all shapes and sizes, international competition in our main domestic tournament, Olympics, women's team on the world stage, muti-faceted game structure (all the contests within a contest). Celebrate and promote all these things, educate people about the game, don't just try and market the game like every other sport does ('hard hitting action' type stuff...there is no point of difference in that).
The 'brand' of rugby has to do everything it can to end its association as being elitist and snobby, but that doesn't mean having to be like the NRL or AFL. Players being articulate and outspoken is actually a good thing for the game. Pocock's activism, whether you agree with him or not is great because there's no other sportsman like him! Same, on a completely different level, with Nic Cummins. Like Cheika has done with the Wallabies culture, the ARU should embrace all of these different characters. The more interesting characters the better. It stands out in an age of highly media trained, cliched sports people all with the same personality.
Also, I think the key focus on growing the game should be at super rugby level (and to a lesser extent the NRC) rather than through the Wallabies or simply through the grassroots. Call it a 'middle out' strategy. Super rugby could be one of the great globally popular sporting leagues - and the only one which is actually global. We need 6 huge rugby teams in Australia - with the Wallabies being just one of them. I think it's the key to competing with the other codes. The Wallabies can't be everywhere at once.
