As each side makes their preparations for the upcoming trade period, we have taken a look at how each club stacks up in talent, age and experience to see how close they are to contending for a flag.
See how we've marked every club's premiership window.
Although the Crows have never bottomed out, with the club's 14th placed finish in 2011 the lowest in their 29-year history, the 2020 season could be their toughest. After failing to make the finals for the second straight season, the club are not just on the verge of a list overhaul, but a complete reset of the club and its operations.
Head coach Don Pyke has already resigned and a whole host of experienced players are expected to follow him out the door. However, with the likes of Rory Sloane, Brodie Smith and Rory Laird remaining at the club, the Crows still have enough talent to remain competitive next season.
2020 could be the one step back Adelaide needs to take two steps forward, but only time will tell how their squad forms under the new head coach.
Verdict: Closed shut
The Lions qualified for their first finals series since 2009 and despite going out in straight sets, the club showed plenty of promise and can only build on their success in 2020. Led by coach Chris Fagan, Brisbane surged up the ladder this season on the back of their young stars.
With an average age of just 22.6, the second-youngest in the league, Brisbane's youthful list is still yet to enter its prime. Although they failed to make it count on the biggest stage in 2019, the experienced garnered will hold them in good stead as they undoubtedly return to the finals next year.
Brisbane had the quality to make the finals this year but not the experience to finish the job. Next year, they could go further.
Verdict: Opening up
This time last year the Blues were in dangerous territory, winning the wooden spoon for the second time in four years and failing to attract big name players. 12 months later and Carlton are now a destination club, under a new head coach and armed with a deadly midfield duo, the Blues are expected to climb up the ladder in 2020.
For the past few seasons, Carlton's premiership window has been nailed shut, but it appears the club have finally found a screwdriver. Patrick Cripps is now a superstar of the competition and rookie Sam Walsh isn't too far behind him. Youngsters Charlie Curnow and Sam Petrevski-Seton have also become household names and Princes Park has emerged as an attractive home for rival players.
The Blues still have plenty of work to do before they secure their first premiership since 1995, but the club finally look like they're heading in the right direction.
Verdict: Creaking open
Collingwood suffered another finals heartbreak in 2019 but their premiership hopes for 2020 are still well and truly alive. The Magpies have one of the strongest lists in the competition and after being tested by injuries and suspensions, also have plenty of trust in their depth.
Collingwood have a strong contingent of young match-winners including Jordan De Goey and Adam Treloar, and the club's main priority should be keeping these men fully fit. However, the clock is ticking for with captain Scott Pendlebury on the wrong side of 30 and key players such as Steele Sidebottom and Dayne Beams not getting any younger.
Although the Pies have a plethora of young talent, if they are to win their 16th premiership, they will need to do so in the near future.
Verdict: Open
The Bombers were hard to get a read on this year. Although they finished eighth and made the finals, their 2019 was far from convincing. Marquee recruit Dylan Shiel was an integral player for Essendon, but much like the entire team, was inconsistent and often lacked polish.
The Bombers were impressive at times this season, especially during their resounding win over Brisbane in round four and their come-from-behind victory over Grand Finalists GWS in round 15. However, they are still one or two pieces away from becoming a contender, including a strong-bodied midfielder to compliment Shiel and best-and-fairest winner Zach Merrett.
2020 could go either way for the Bombers and this off-season will be crucial in determining whether or not Essendon will become contenders in the future. The potential losses of Joe Daniher and Orazio Fantasia could really flip their narrative.
Verdict: Slightly ajar
Fremantle have had a good start to their off-season, with captain Nat Fyfe securing his second Brownlow and former Docker Justin Longmuir taking the reins after Ross Lyon's departure. However, Freo haven't reached the finals since 2015 and have one of the most inexperienced lists in the competition.
Although Fyfe and mercurial forward Michael Walters are amongst the league's elite, Fremantle's list could suffer a setback with key pair Bradley Hill and Ed Langdon expected to move back to Victoria.
However, if Longmuir can reinvigorate the stagnant careers of Jesse Hogan and Cam McCarthy and find adequate replacements for Hill and Langdon, the Freo rebuild could be finished sooner rather than later.
Verdict: Closed
The second half of the 2019 season will be filled with plenty of regret for head coach Chris Scott. Although the Cats managed to hold onto top spot, the club failed in the finals once again and lost seven of their final 13 games.
Although Geelong did have their problems, they were still the best defence in the league and have an abundance of young talent at their disposal. Gary Ablett, Joel Selwood and Tom Hawkins are all entering the twilight of their careers, but the Cats have an apt ability to turnover their squad and still remain competitive.
Losing Tim Kelly will dent their chances but Geelong's window could stay open for at least another year or two.
Verdict: Closing
Gold Coast are a rabble, there's no debating that and their premiership window is consequentially the furthest away out of any club. The Suns, who have never tasted finals footy, could only watch on as fellow expansion club GWS made their first Grand Final this year.
However, despite their obvious shortcomings, the Suns have been blessed with a horde of draft picks and have every opportunity to build a contender, with their cap space also an attractive proposition for potential targets. But there is no point drafting players or trading for them if you can't keep them at the club, and that will be Stewie Dew's biggest challenge.
Gold Coast will not only be fighting to stay off the bottom next year, but they will also be fighting to keep their star recruits happy and out of the clutches of their rivals.
Verdict: Closed shut
Although their demoralising Grand Final defeat will weigh heavily on the minds of everybody involved, GWS have the quality and now the experience to do it all again and do it better. The Giants list is poised for a prolonged tilt at an inaugural premiership, with an average age of 23.4 and an average games played of 75.1.
GWS have a perfect mix within their squad, with the energy and intensity of players like Tim Taranto and Josh Kelly complimenting the experience and maturity of leaders such as Phil Davis and Callan Ward. The Giants also benefitted from their injury struggles as youngsters Sam Taylor and Brent Daniels featured prominently in their finals campaign.
GWS have enough talent to win a premiership, the only question now is if they have the resilience to bounce back from their humiliation and exact revenge.
Verdict: Open
Hawthorn boasted the oldest and most experienced list in the competition in 2019, but it is their young core which will keep the Hawks in the hunt for another flag. With Tom Mitchell set to return, Jaeger O'Meara finding his feet and Ricky Henderson enjoying a renaissance, the Hawthorn midfield will be an imposing force next year.
Alastair Clarkson also has versatile swingmen James Sicily and Jack Gunston at his disposal and is expected to add more quality in the form of former number one pick Jon Patton. Despite finishing ninth, the Hawks won six of their last eight, including victories over Collingwood, Geelong and GWS, which is encouraging heading into next season.
With 'Clarko' at the helm, Hawthorn will always be a threat and will be back in September action very soon.
Verdict: Getting wider
The Demons were one of the most hyped teams headed into the 2019 season, with many expecting the 12-time wooden spoon winners to finally end their seasons of misery and enjoy a prolonged period of success. That couldn't be further from the truth as Simon Goodwin's side slipped to 17th spot at season's end after finishing fifth the season prior.
On paper, the Melbourne team is good enough to challenge for a premiership. Max Gawn is one of the league's top ruckman and Clayton Oliver is a superb accumulator of the ball. However, the club has the second-worst defence in the competition and struggled to convert up forward, conceding an average of 91 points per game, and only scoring an average of 71.
Melbourne have a boatload of talent and a whole offseason to turn things around, but it will be interesting to see if 2018 was just a fluke or a sign of things to come.
Verdict: Slightly ajar
While North Melbourne still had their issues, under Rhyce Shaw they looked a much more improved side, most notably in their 86-point victory over Port Adelaide. Experienced campaigners Shaun Higgins, Ben Cunnington and Todd Goldstein are crucial, but it is the development of the next crop of players such as Tarryn Thomas, Luke Davies-Uniacke and Jy Simpkin which will decide the club's success.
The Kangaroos has an uninspiring 2019 season, finishing 12th and struggling to maintain consistency throughout the year. However, they were top-eight for points scored, led by the second-best goal-kicker in the league, Ben Brown. The Kangaroos also conceded just 51 inside 50s per game, the third-best in the league.
A premiership is long way away for Rhyce Shaw but North Melbourne have plenty of positives to build on going into 2020 and a finals berth is not beyond them.
Verdict: Closed
After taking three players in the first round of the 2018 Draft, the Power had one eye on the future in 2019, but that does not excuse the vast gap between their best and worst performances. Ken Hinkley's men missed the finals for the fourth time in five years and their ageing superstars will be cause for concern.
But it wasn't all doom and gloom for the Power this year, with the club leading the league for inside 50 differential and showcasing the ability of future stars Connor Rozee and Xavier Duursma. The Power also chalked up encouraging victories over eventual top eight sides West Coast and Geelong, but this year will be seen as a failure by Port fans.
With Travis Boak and Robbie Gray both 31 and Justin Westhoff 32, time is running out for the Power to secure a premiership with their current group.
Verdict: Closing soon
The 2017 and 2019 Premiers are the best team in the league with daylight second and have every chance to start a dynasty which rivals Hawthorn's. After their disappointing Preliminary Final defeat last year and having key players suffer serious injuries, the Tigers have brushed it all off and blown opposing teams out of the water.
Richmond have a very experienced group, with an average of 79.1 games, but are only the 10th oldest side in the competition, with an average age of 23.2. Although older leaders such as Trent Cotchin and Jack Riewoldt have been a crucial factor in the club's success, players like Jack Graham and Tom Lynch are ready to fill their shoes if needed and keep the good times rolling.
The Tigers will welcome back Alex Rance into one of the AFL's best defences and will be the favourites to go back-to-back.
Verdict: Wide open
The Saints are still a long way away from contending, but with many names linked to Moorabbin and Pick No. 6 in hand, the club can take a big step forward this off-season. Head coach Brett Ratten, who took over in mid-season, will have the task of finally finishing St Kilda's rebuild, which has left the club without finals since 2011.
Ratten will have an impressive young group of players to develop, with Jack Billings, Jade Gresham and Rowan Marshall showing signs of brilliance this year. However, flashes of brilliance aren't enough to win premierships and the Saints still lack any elite superstars which can lead a club back up from the depths.
St Kilda have the potential to return to the big dance, but it will take many more games of experience and many more wins before it eventuates.
Verdict: Closed shut
2019 was the first time Sydney had missed the finals in nine years and it spelt the end for the careers of many senior players. However, with the club committing to coach John Longmire and emerging stars Isaac Heeney, Callum Mills and Nick Blakey gaining more experience, a return to September may be sooner than expected.
The Swans were poor this season, finishing 15th and struggling to get an ageing Lance Franklin out of the medical room and on the field. But it does provide Sydney with the opportunity to replace their retiring players with youth through the draft or target proven players from other clubs.
If the Swans can lure Daniher then their window will get a little wider but at this stage there are more questions than answers.
Verdict: Barely open
After winning the premiership just as year ago, the Eagles are sure to be up there again next season. Nic Naitanui is back and Tim Kelly could be on his way so their time in the sun is far from over, but there are some wrinkles which need to be ironed out.
The biggest issue for Adam Simpson is Josh Kennedy, the former two-time Coleman Medallist kicked just 49 goals this season, his worst return in an injury-free year since 2010, and at 32, it may never improve. With captain Shannon Hurn also in the twilight of his career and the future of Willie Rioli in question big decisions will have to be made in 2020.
West Coast still have Gaff, Darling and Shuey at the peak of their powers so their premiership hunt is far from over, but it could be winding down.
Verdict: Open
Many neutral supporters were hoping the Bulldogs could pull off another fairytale finals run in 2019 but it wasn't to be. It is certainly not out of the question for 2020 though, with Luke Beveridge's men, led by three-time best-and-fairest winner Marcus Bontempelli, younger, but more experienced than their 2016 counterparts.
The Bulldogs have talent oozing out of their pockets with Bontempelli, Jack Macrae, Josh Dunkley and Aaron Naughton all lighting up the competition. However, the Bulldogs weren't without their problems, namely their defence which conceded 100+ points on seven occasions including their Elimination Final loss.
With another season of experience under their belt, the Western Bulldogs' young brigade are primed for another push at premiership glory in 2020.
Verdict: Opening
