I guess it's kind of a good thing picking it up now, because you've got the off-season to study the rules, players and history, and then when the season gets underway it's not like you've got no idea what's going on
Die hard Packers fan here.
NFL is such a good change of pace from the frantic game of aussie rules and it conveniently begins just as the footy is ending.
There's numerous guides on YouTube as to how the game/league works so you'll have no issue learning about the sport I'm sure
For me it was honestly boring, found myself just browsing on my phone for an excuse to not watch it. Last year I thought they could only improve upon the format, and had it not been my Mum's birthday, I might've actually gone. But no, rules are more convoluted which is funny seeming they're trying to export this to markets who don't even know Aussie Rules.
The precedent has been set by the AFL that they are willing to risk the health of players pre-season, so why not turn this charade into a State of Origin Carnival? There's no excuse now.
23,000 at AFLX (cough... free tickets ... cough), you could likely sell out Marvel with a State of Origin Game there.
The last two games when the players started to get competitive I found it relatively entertaining. It's nowhere near the standard of actual footy but it was still a reasonable product to watch. Not a disaster in my book, hopefully they just keep improving the format in the future.
