While the grunt work is typically done by the midfield of an AFL side, the heavy lifting can often be done by the backline, especially for teams at the lower end of the ladder.

Premiership defences require potent key defenders, intercepters and running ball-users to provide an offensive threat.

Geelong were an unstoppable force out of defence last season, with De Koning and Stewart constantly preventing chaos and allowing ThuoyThou, Guthrie and others to control the ball effectively.

Melbourne were unbeatable at their best in 2021 with Lever, May, Petty and even Gawn maintaining control of the game with their aerial presence while Salem, Brayshaw and Rivers inflicted damage by foot.

This list will help you decide which team will be the immovable object in 2023 and here we look at the backlines ranked 12-7.

5. (8th) Richmond

This Richmond side does not have the same defensive presence as they did in their premiership years, but Tigers fans will hold faith in their experience and system.

Robbie Tarrant had a solid first year in the yellow and black but is probably not a desirable number-one key defender on a premiership team. Dylan Grimes and Noah Balta, however, provide excellent backup which could make up for any tall defensive deficiencies.

Daniel Rioli and Liam Baker also provide an excellent presence as small defenders and back-line ball users, both being able to roam forward as a goal threat. Jayden Short may also play this role when resting from a midfield spell.

Nick Vlastuin, Nathan Broad and sophomore Josh Gibcus are all quality defenders who may be tussling for a spot in the back six; all would be stiff to miss out given their ability.

Beyond that, Richmond are stacked with young players capable of playing down back when their time comes. Hugo Ralphsmith, Sam Banks, Tom Brown, Rhyan Mansell, Bigoa Nyuon, Kaleb Smith and Tylar Young will all be in for a year of development while their side looks to contend.
