You would have played the first placed Saints in Melbourne though, not WC(?) at home. A much more difficult (but not impossible) game.
Adelaide did end up playing the first placed Saints in Melbourne a few weeks later. Adelaide won by six goals.
To show you how ridiculous that finals system was Geelong finished 2nd. Lost to North first week and had to travel to Adelaide. Reasons like this is why it was changed to give the top 4 a bigger advantage.
Perfectly reasonable. Geelong lost the first final, but they did not get eliminated, but they did lose their "2nd spot" ranking as a consequence of losing. Adelaide finished 4th, and then won their first final, so as a consequence they were then re-ranked higher than Geelong.
This happens in the normal minor rounds. A team was ranked 2nd, but loses, and another team which was ranked a bit lower wins, and hey presto the very next week the team that was 2nd is 2nd no longer!
Imagine that.
