What do they like Football or American Gridiron?

Overweight fairies? NFL players may not win the game, but they would beat the snot out of these Aussie players. Ray Lewis would kill anybody that came near him. Look at some of the sizes and speed numbers on some of these guys. Calvin Johnson, Demarcus Ware, Vernon Davis, Andre Johnson, etc. are all miles ahead on anybody in Aussie football in terms of athleticism. My question is why make the comparision? Both sports are incredible in their own way.
