Footy Grand Final

This weekend I observed my first footy Grand Final. The Grand Final is similar in importance to the Super Bowl. Australian Rules football or "footy" is best described as a cross between rugby and soccer. Here is what I understand so far:
Two teams play on a gigantic oval field. In Melbourne, they play at the Melbourne Cricket Ground, better known as the MCG. The stadium is huge. The playing field is: 160m x 139m. In American football, the field is 109.7m × 48.8m.
The game is played during 4 quarters of 20 minutes each, with 18 players from each team on the field. The ball is similar to an American football, only it is just a little more plump and the ends are more rounded. When a player is in possession of the ball, he needs to bounce or pass it about every 15 meters (49ft or 16 yards). The main two types of passes are kicking or handballing, which is like an under-hand volleyball serve.
A goal can only be scored with a kick. The goal posts configuration is similar to this "I I I I". A goal through the center posts is worth 6 points. If it is kicked through the outer posts on either side, it is worth 1 point.
If a player catches a kick that is more than 15m, that is considered a "mark" and the player can kick for a goal.
It is not unusual for scores to get into the high double digits. This year the 2 teams were St. Kilda Football Club and the Geelong Cats (ja-long). Geelong pulled it out in the last 2 quarters winning 80-68.
The final notable element is the player uniform. There are no pads to hide behind. These guys are in tip top shape. The jerseys are sleeveless and the shorts are, well, short. This is a perfect sport for the sport-less crowd, as the view is always nice.
