Their run of 15 wins from their final 18 matches this season saw the Swans ultimately fall to Geelong in the semi-final, but it's enough for the betting agencies to label Sydney as the team to beat in 2018.
The Swans are listed at $4 with TAB.com.au to win the premiership, and are also the favourites to finish in top spot, paying $3.50 for the minor premiership.
Adelaide ($5) and GWS ($6) are the two sides trailing the Swans, while Richmond are quite short as well on the back of a stand-out 2017 campaign.
The Tigers - who will move into the grand final with a win over the Giants on Saturday - round out the top four at $8, and are the only four sides in single digits.
Geelong are the longest odds of any of the four preliminary final sides left in 2017, as they're currently paying $11 to take out the crown in 2018.
Betting agencies are predicting big things from both Collingwood and Melbourne next season, as both the Pies and Demons are at just $17 for the flag, despite failing to qualify for September action in 2017.
