I think the G&G public is generally quite intelligent when it comes to rugby. However, I think the rugby public in general are not.
At any rugby game there's sooo many people yelling out at the ref for correct calls, yelling at their own team for taking sensible kick options, and yelling at guys for "not trying". None of it is grounded in anything.
The same could be said for politics, cinema, or any other sport. People know their things (their job + hobby) but are generally ridiculously uninformed about everything else and are still looking to have options on it, so they turn to the mainstream mass media to get informed.
That's where opinions like, say, "the Reds play the most running style of rugby in Aus" come from. It's not 100% wrong but the Rebels run it far, far more often AND the Reds pick-and-drive more than any other Aussie side. Truth is in the eyes of the beholder and the media very much dictate that.
I think the media does create and change public opinion, but you're right it's not that simple. Often, they find a thread to tug and when it works, they tug at it hard.
If I decided to get every Fairfax journo together tomorrow and we were all going to write about the injustice of the rising price of cotton bath towels for the next month it wouldn't capture the public's imagination.
But, if I say decided to get every Fairfax journo to write about Japan's whaling practises for a month I'd get plenty of mainstream outrage, and that old chestnut has been out there for years.
I actually think a Gagger podcast/article surrounding the sporting media and the fallacies around it would be amazing. Maybe another night, it's getting late and I've got plenty of rugby to get through tomorrow.
Though, to further my point about media BS, at the game tonight Cooper Vuna got MotM. He scored two tries BUT he directly let in 2 from being a weak link in the slide defense and indirectly let in one from a horrendous kick return option (one of the worst I've seen at Super Rugby level).
Media perception V reality. I'm sure the highlights package will make it look like a game for the ages.
