I would think that it will come down to the occassion. Sydney will be ready to go, they have a team full of contributors and the moment will not overcome them.
West Coast however have the class. But they also have an inexperienced forward line. Admittedly it has held up so far for them, but the Grand Final is a completely different ball game.

This for me is where the game will be decided. My tip is that it will be a nervous start from the Eagles, with Sydney playing the hard ball. Close to 3 quarter time, and the Eagles will steady and bang the goals on to win reasonably easily.

For me, West Coast by more than 5 goals. But nothing would surprise.

All I can ask is that the game is worthy of all the beers I will be drinking, imagining what could have been... Again....
