Heading into the final game of the home and away season, there are four teams vying for two positions in the top eight.
Fremantle, alongside GWS, Essendon and West Coast all have varying chances of playing finals.
Here's the scenario for each team.
Fremantle (10th), 10-11, 40 points, 89%
Opponent: St Kilda (A)
The scenario: Fremantle need to beat St Kilda and have two of GWS, Essendon and West Coast lose. For example, if Fremantle win, they still get through if GWS win providing both Essendon and West Coast lose. There is no likely scenario where Fremantle can make finals with a loss due to Essendon's superior percentage.
GWS (7th) 10-10-1, 42 points, 98.9%
Opponent: Carlton (A)
The scenario: Win and they're in. GWS would also remain in the top eight with a loss providing two of Essendon, West Coast and Fremantle lose.
Essendon (8th) 10-11, 40 points, 107.2%
Opponent: Collingwood
The scenario: Due to their significantly better percentage than the other teams on 40 points (West Coast and Fremantle), a win for the Bombers would virtually guarantee a top-eight spot. The Bombers would still make finals with a loss providing West Coast and Fremantle also lose.
West Coast (9th), 10-11, 40 points, 94.9%
Opponent: Brisbane (A)
The scenario: West Coast need to win and have one of GWS and Essendon lose.
Let's get technical...
Ok, so technically, we haven't taken into account every possible scenario. In some very extreme cases, teams could get through to the finals on the back of some big wins and heavy defeats for other teams in the running.
For example...
Technically, Richmond and St Kilda are on 36 points and can also make finals. It would require all teams on 40 points to lose (Essendon, West Coast and Fremantle). Due to Essendon's superior percentage (107.2) compared to Richmond (97.8) and St Kilda (88), it would require a very heavy Essendon loss (100+) and a very big win (100+) on their part to have any chance of getting through.
There's also a slim chance, if Fremantle win, for Freo to get through with a West Coast win providing one of GWS and Essendon lose. For that to happen it would require Fremantle to jump West Coast on percentage with win of more than 100 points and a narrow West Coast win.
