THE two extremes of football will go head-to- head tomorrow.
The toughest, most ferocious defence we've ever seen facing up against one of the most dangerous attacking line-ups.
It was frightening to watch Fremantle's forward- press in action last week against Sydney.
So focused, so desperate to lock that ball inside forward 50.
Tackle after tackle was sticking, with the Swans at times having multiple Dockers hanging of them.
It was football as "down and dirty" as we've ever seen it.
While the Dockers build their game around this ferocity in their front-half, Hawthorn uses this area of the ground so well itself.
The Hawks build so many of their attacks from the back-line, through their sublimely skilled defenders.
When you have Grant Birchall and Brent Guerra leading the charge in this department, you know you are onto a good thing.
Birchall and Guerra often go at a disposal efficiency rate in the high 80 per cent range, and its other options out of defence (Josh Gibson, Shaun Burgoyne, Luke Hodge among them) also barely waste a possession when leaving the defensive 50.
As simple as it sounds, Ross Lyon's mantra here will be to make these "supermen" from defence look like mere mortals.
This won't be an easy task, as the Hawthorn team is one of the most skilled around for quite a while, with its ball movement at times beautiful.
It then has the luxury that when it does flow into attack, it has options a plenty.
Lance Franklin, Jarryd Roughead, Cyril Rioli, Luke Breust, Paul Puopolo, Jack Gunston, Bradley Hill, David Hale ... the list of attacking options seems endless.
While Hawthorn is a much "prettier" football picture, that's not to say the Dockers are completely "ugly".
Michael Walters, Chris Mayne and Hayden Ballantyne are not only the masters of frontal pressure, but are all capable of kicking a bag of goals, while Matthew Pavlich looks primed now after 291 games he has finally got a chance at the big one.
Midfield-wise Michael Barlow, David Mundy and Nat Fyfe are three of the best, and will certainly be able to hold their own.
The Hawks have "hard nuts" though in Sam Mitchell, Jordan Lewis, Luke Hodge and Brad Sewell, who should all relish the oncoming storm that Fremantle is likely to bring.
In many ways, picking the winner of this one is the footy equivalent of throwing darts while blindfolded.
You can usually go back and get some idea about what type of contest you will get based on recent history, but in this case there is no recent history.
In the Lyon-era, they have met twice, once each in the past two years, with the Hawks winning both.
So what can we get out of their only meeting this year?
The Hawks won this game on two fronts, better outside run and a strong forward set-up.
But so many pieces of tomorrow's puzzle were missing.
Aaron Sandilands didn't play, neither Pavlich or Brian Lake played, or Franklin's likely opponent Luke McPharlin.
The one thing you can take from it is that Hawthorn, and in particular Franklin and Roughead, were able to have as much scoreboard (118) impact than anyone this year against Fremantle.
In fact, due to Fremantle's constant visits to Tasmania, there's not even an advantage in Melbourne for the Hawks, having only played them once at the MCG.
While so much focus will be on the "inside" battles here, I'm tipping whichever team can get on top with its outside run will win.
If Rioli, Bradley Hill, and Isaac Smith can have more impact than say Stephen Hill and Danyle Pearce, then the Hawks should win.
Freo's key man, as it has been for much of the year, is tagger Ryan Crowley. If he can limit Mitchell, then the Dockers will be well on their way.
For the Hawks, ruck duo Max Bailey and David Hale will be important.
Sandilands will get first hands on the ball, but the Hawks duo must show some competition and have an impact around the ground.
If Hale can have an impact in attack, it could nullify the output of the 211centimetre giant from Western Australia.
This will be a tough contest and while Fremantle's pressure and the wet weather will impact on Hawthorn's ball use, the Hawks forwards will still see enough of it to eke out a win.
Throw in their determination not to have another wasted season, it will do enough to get home.
But only just.
ALEX FAIR'S TIP: Hawthorn by eight points.
NORM SMITH: Brad Sewell.
