Despite all you've seen, heard, smelt, felt and tasted this week, this derby is not all about Freo.
West Coast need to perform here.
They have GWS and the Crows on their ladder heels.
A loss could put top 2 in danger.
A loss followed by a loss to Collingwood next week could put top 4 in danger.
They've lost more quarters than they've won this year.
Their game hinges on Yeo and Cripps (ha!) and the greenish-yellowy dressed bunch more than just about anything else.
They are favourites, and despite all the talk of derby results being unpredictable, just how many have actually been won by the odds-on underdog? Very few.
The heat is all on them. They woudn't want to drop the ball here...hey, Jack.
Pressure!
