The Brisbane Lions are considered as one of the youngest lists in the game, ranked fifth youngest behind Gold Coast, Carlton, Richmond and North Melbourne. 

The average age of a Lions player is 23-years-old with only 9 players having reached the 100 game milestone so far.

As the team heads into 2018, there will be 11 Lions hopefuls waiting to make their debut.

Clubs ranked from oldest average age to youngest

Interestingly, reigning Premiers Richmond Tigers are the third youngest list ahead of the 2018 season.  

After entering 2017 having played 65 finals collectively – compared to Hawthorn's 313 and Sydney's 267 – last year's premiership run has given the Tigers 114 games of September experience.

Gold Coast is the least experienced team in finals, with captain Gary Ablett taking his 17 games of September experience with him to Geelong and dropping the Suns' total to 31.

St Kilda (32) and Melbourne (44) are also very green when it comes to playing finals and both will be expecting to add experience in 2018.

Only six clubs have fewer than 100 games finals experience, with Carlton (56), Essendon (63) and the Brisbane Lions (65) the others.

Three clubs will go into next season with five 200-game players – Geelong, Port Adelaide and Sydney – while St Kilda will have none after the retirements of Nick Riewoldt, Leigh Montagna and Sean Dempster.

West Coast has the most players on its list yet to debut with 16 after adding six players through the national draft and three new rookies.
