I've just reviewed the current TAB AFL Futures markets in light of the recent simulations I performed of the remainder of the season, and the only value bets at the moment (assuming you agree with the MARS Ratings I've used in the simulations) are: 

• Geelong to Make the Final 8 : offers an estimated 6% edge at $1.10
• Geelong to Make the Top 4 : offers an estimated 14% edge at $8
• St Kilda to Miss the Top 8 : offers an estimated 11% edge at $1.40
• GWS to Win the Spoon : offers an estimated 4% edge at $1.40
