Are you kidding? It's twice as fast as either, played on a ground almost twice the size and no rugby or US footballer could possibly play it - they'd be knackered after one quarter.
I saw some once and I remember thinking that the Aussies must think American football players are a bunch of sissies with their padding and their helmets.
I saw some women's Aussie football during last year's Summer Olympics. Am I right? I wouldn't want to tangle with any of those women and I'd hate to see what the men look like.
