GEELONG coach Mark Thompson says his side has quietly been adding new elements to its game in preparation for whatever is thrown its way in September.

The Cats, who have won a staggering 39 of their past 41 matches, will head into the finals the shortest-priced premiership favourite in history.

Their dominance is likely to see rival teams attempt a range of tactics in a bid to unsettle and outplay the all-conquering side, which has lost just once this season.

But Geelong will head into its finals campaign armed with what it hopes are the tools to deflect whatever any opposition might try as it prepares to scale the AFL's highest mountain for the second straight year.

"What we've been doing for about the past six or seven weeks is just throwing little things into our game to play a variety of oppositions," Thompson said.

"That's a little bit about what we think we're going to expect in the finals.

"It's sort of an ongoing thing but it's nothing specific that you can say, 'Yeah, we're going to do this against this team'."

At times against North Melbourne on Sunday Geelong appeared to be playing a full ground zone.

On more than one occasion, with the ball in dispute in the midfield or in Geelong's half, the Kangaroos had a loose man inside their attacking 50 as the Cats' defenders pushed up.

As a result, when the Kangaroos gained possession they often struggled to get the ball past half-forward, which led in part to the massive discrepancy in the inside 50 count – 64-36.

"The earlier time we played them they tried to take a lot of our boys deep and we just said, 'Well, we're not going to accept that'. And we didn't," Thompson said.

While fellow top-four teams Hawthorn and the Western Bulldogs have known their first-week finals destiny for some time, the best team in the competition has had to sit back and wait.

Thompson and his players won't know who they will take on in their Qualifying Final until the completion of this round, something the Cats coach believes has its pros and cons.

"If you knew you were playing someone you'd probably just really study them," he said.

"It might be a good thing that we're studying all of them and keeping an eye on the whole finals series."

Geelong is a chance to play any of four teams – North Melbourne, Collingwood, Adelaide or St Kilda – although Thompson believes it's more than likely the Cats will play the Kangaroos.

"I read somewhere that the Kangas, if they lose and some teams win, then they can end up eighth, which is just amazing going into round 22," he said.

"When we finish playing we'll find out what happened. We probably won't keep an eye on it during the match."
