Yeah they show it in Aus, Don whatshisname usually calls it/intros. Middle of the night. Of course, the game is so confusing that no-one knows what the hell is going on. Especially when compared to a much faster Aussie Rules Footy with a playing field easily twice as large, and no wussy pads/protection. Of course there's no requirement for 300+pound players in AFL either.
I pretty much understand the general gist of NFL, now that I'm watching my fourth season.
