I dont think they are finished. They may not win the GF but they will make the 8. The only bad game they really have had was against Hawthorn.

West Coast and sydney always play well against brisbane no matter where it is.

Dont forget west coast also beat them in 2003 by 70 or so points at the gabba.

They arent playing as a team but im sure that will change over the next couple of weeks and they will back to some type of form.

From memory i dont think brisbane has beaten west coast for 3-4years so it was no major shock they got thumped by them again.
