AFL Game Styles: Flooding, Press and the Corridor

Australian football is the only major code played on a ground with no fixed dimensions, with eighteen players a side, no offside line and no restriction on where anybody may stand. That combination makes it the most tactically open team sport in the country and the hardest to coach. Any honest attempt to get AFL tactics explained has to start there, because every named game style in the sport's history has been an answer to the same question: how do you organise eighteen people across roughly two hectares of grass when the rules give you almost no help?

The short answer is that for a century the sport barely tried. Players held positions, matched up on a direct opponent, and the ball moved forward in a rough line. From about 1990 that broke down, and in the thirty-odd years since, Australian football has cycled through flooding, zone defence, the cluster, the forward press, possession football, handball chains and forward-half pressure. Each one worked until enough coaches copied it, and each one prompted the AFL to change a rule in response.

This page walks through those styles in the order they arrived, explains the language you will hear on a Friday night broadcast, and sets out what the 2026 rule package is likely to do to the way clubs set up. It is a companion to two other pages in this section: AFL interchange rotations and the cap, which covers the fitness engine that makes modern structures possible, and the AFL set shot, which covers what happens once all this tactical work produces a shot.

AFL tactics explained: what a game style actually is

A game style is a club's agreed set of defaults. It answers four questions. Where do we stand when the ball is in dispute? Where do we kick when we win it? How far up the ground do our forwards defend? And how much risk will we accept in our own defensive fifty?

Everything else is detail. A senior coach cannot direct eighteen players in real time, so the job is to install enough shared rules that players make the same decision without being told. When commentators say a side "knows its game", they mean the defaults are automatic. When they say a team "played on instinct", they usually mean the defaults failed.

The reason game styles matter so much in Australian football is that possession is genuinely contested. Unlike association football, where a team can hold the ball for two minutes with no opposition contact, an AFL side that stops moving gets tackled. Every possession chain is on a clock. A game style is really a plan for spending the four or five seconds a player has before pressure arrives.

Why the ground itself sets the tactics

No two AFL grounds are the same shape, which is not true of the rectangular codes. That single fact drives more tactical variation than any rule.

The Melbourne Cricket Ground is roughly 160 metres by 141, wide enough that a switch across the ground genuinely creates space on the far wing. Marvel Stadium is about 160 by 129, some twelve metres narrower, and that missing width changes everything. The corridor is tighter, a defensive zone can cover the full width with fewer bodies, and the game becomes more territorial and more physical.

Adelaide Oval has its own quirks with a long, comparatively narrow playing surface, the Gabba is round and tight, and Optus Stadium in Perth is generous by modern standards. Interstate clubs build their default structures around the ground they train on, which is one reason home-ground advantage in the AFL is larger than in most leagues that do not involve a five-hour flight. The Australian cricket grounds guide covers the dimensions of the shared venues in more detail.

Man on man: the default before 1990

For most of the VFL's history the game was played as eighteen individual contests. A full-forward stood in the goal square with a full-back on him. Each player had a direct opponent, and coaching was mostly about winning your own duel and running harder than the person you were paired with.

Interchange did not exist in a meaningful sense. Two reserves were permitted from 1946 and the modern rolling bench only arrived in 1978, so a player who started at centre half-back was generally still there in the last quarter. That alone kept the game spread out. Nobody had the aerobic capacity to leave a position, contest a stoppage sixty metres away and get back.

The tactical vocabulary of the era was small: the tagger, the run-with player, the loose man in defence. Kevin Sheedy at Essendon and Allan Jeans at Hawthorn were considered radical for moving players between lines mid-game. Hawthorn's 1980s sides ran the ball in waves using multiple handballs to draw an opponent before releasing, which was borrowed loosely from rugby thinking and was about as structural as football got.

Pagan's Paddock and the manufactured space

The first named, deliberate spatial tactic most supporters can recall is Denis Pagan's at North Melbourne in the 1990s. The idea was blunt: order every attacking player out of the forward fifty, leave a single dominant key forward inside it, and bomb the ball long into the empty arc.

It worked because North had a forward who beat any single opponent in the air or at ground level. It also worked because nobody had yet decided to leave a spare defender free. Pagan's Paddock was, in effect, a way of manufacturing a one-on-one contest in an era when one-on-one contests were assumed.

The counter was obvious once someone tried it. Leave a third tall in the hole in front of the contest and the long bomb becomes an intercept mark. That single adjustment is the origin of the modern loose defender, and from it flows every zone and every flood that followed. Pagan's Paddock is the last great attacking tactic that assumed the opposition would keep playing man on man.

Flooding: the tactic everybody blamed

Flooding is the release of forwards back into the defensive half to deny the opposition space. The Western Bulldogs used a version against Essendon in 2000 to end a long winning run, and it is the moment usually cited as the tactic entering the public conversation.

Rodney Eade's Sydney sides took it further. Eade used the confines of the Sydney Cricket Ground, which is small by AFL standards, to block the corridor by pushing players up a line whenever the opposition had the ball. Eade has since said the players took the idea further than he intended, to the point where nearly the whole side was in the defensive half. It smothered the opposition's forward entries. It also made scoring almost impossible for Sydney, because there was nobody left ahead of the ball.

That is the permanent trade-off in flooding and it has never been solved. Every player you put behind the ball is a player who is not available when you win it back. Flooding was blamed for ugly football through the mid-2000s and drew enormous criticism, but it was never illegal and it never really disappeared. It just became more sophisticated.

1. 1Set the gridPlayers take up spaces rather than direct opponents, spread across the width of the ground in three loose lines.
2. 2Force the boundaryThe front line angles its body to close the corridor so the only available kick is towards the boundary line.
3. 3Shift as oneWhen the ball moves sideways the entire grid slides with it, holding the same relative spacing.
4. 4Trigger the pressOnce the ball carrier is committed to a boundary lane, the nearest defenders squeeze in to make the target contested.
5. 5Win the turnoverThe kick lands in a contest, the ball spills, and the zone converts instantly into a running attack in the other direction.

A simplified description of the shape most AFL clubs run when defending a kick-in or a switch. Clubs do not publish their structures and details differ from side to side.

Zone defence arrives from basketball

Zone defence, in which players guard areas rather than opponents, came into Australian football from basketball and is usually credited to Kevin Sheedy as the first serious adopter. The basic version spreads defenders about twenty metres apart inside the defensive arc so that no kick into the fifty finds a clean one-on-one.

The important shift is conceptual. Under man-on-man defence, a defender's job is to beat his opponent. Under a zone, a defender's job is to make sure the ball never arrives in good condition. Individual match-ups become secondary to the shape of the whole unit.

Zones are why the modern intercept defender exists as a position. A player who is not accountable to a direct opponent can read the flight of the ball and attack it, which is why interception marks became one of the most valued statistics in the game. It is also why the phrase "he lost his man" almost disappeared from commentary. In a zone, nobody has a man to lose.

Clarkson's cluster and the 2008 Grand Final

Alastair Clarkson's Hawthorn side of 2008 took the zone and applied it across the entire ground rather than just in defence. The result was called the cluster, or the rolling zone, and Terry Wallace described it at the time as revolutionary.

What made it different was the commitment. For the cluster to function, three defenders had to leave their direct opponents to form part of a fifteen-man grid, which broke the oldest convention in the sport. The zone then pressed high, aiming to win the ball back as quickly as possible and deliver it to a forward line built around a full-forward who kicked 102 goals that season.

The numbers are instructive because they are not what you would expect. Hawthorn averaged about 51.2 tackles a game, twelfth in the competition, and 109.6 contested possessions, fifteenth. The pressure was not coming from tackling or contested ball at all. It came from having more bodies in the right places, so the opposition's kick was wrong before anyone laid a hand on them. Hawthorn beat a Geelong side that had lost one match all season by 26 points in the Grand Final.

The forward press: Collingwood 2010

Where the cluster corralled, Collingwood's forward press under Mick Malthouse squeezed. When the opposition had the ball deep in its own defensive fifty, every Collingwood player pushed up the ground, compressing all the space between the two arcs into about half the oval.

The opposition then faced a bad choice. Kick short into a wall of players and risk an immediate turnover forty metres from goal, or kick long over the top into a contest with numbers against you. Collingwood led the competition in 2010 with about 74.8 tackles and 56.8 inside fifties a game, and averaged roughly thirty scoring shots.

The press had a clear weakness and every coach could see it. If the opposition executed one long, accurate kick over the top, Collingwood's forwards were seventy metres from their own goal and the ball was in an empty defensive fifty. Sides began carrying a genuinely quick, deep forward specifically to punish it. That arms race is how the modern half-back flanker who runs eight or nine hundred metres a quarter became a required position.

Slingshot football and the Sydney model

Sydney's answer was to invite the press in and then beat it. Slingshot football means absorbing the opposition's forward entries, winning the contested ball on the ground, and then transitioning end to end faster than the opposition can reset its structure.

The Sydney side that won the 2012 premiership under John Longmire, built on the defensive foundations Paul Roos had laid over the previous decade, was the clearest version. It led the league in contested ball at about 151.4 a game, in tackles at about 73.2, and in stoppages at about 28.5. The team did not try to control the game. It tried to make the game chaotic and then be better at chaos than the opposition.

It is worth noting how well this suited a club playing most of its home games at a tight ground in a rugby league city. The Swans could not out-recruit Victorian clubs for outside runners in that era, so they built a style around contested ball, which is the one commodity that can be coached into almost any list. That decision shaped the club for twenty years.

Possession football and tempo

By 2013 Hawthorn had changed again. The cluster had been about winning the ball back; the next version was about never giving it away. Compared with the 2008 premiership side, the 2013 team laid about thirteen more tackles, won roughly 32.6 more contested possessions and seven more clearances a game, and took about twenty-three fewer marks. It scored 114.7 points a game. By 2015 the same club was conceding only about 70.4 points a game.

Possession football relies on the fact that an uncontested kick to a teammate has an expected value far higher than a contested long kick. Teams retain the ball, move it sideways, and wait for the opposition zone to break its shape. Tempo football is the deliberate version, where a side slows the game to a crawl while protecting a lead, then accelerates when the structure ahead of the ball is right.

Crowds dislike both. The AFL has repeatedly tried to legislate against them, most notably with the deliberate out of bounds and insufficient intent rules. Neither the sideways kick nor the slow chain has gone away, because the mathematics behind them has not changed.

Handball chains and the 2016 Western Bulldogs

The Western Bulldogs' 2016 premiership was won with an unusual profile. The side averaged about 199.4 handballs and 263.5 uncontested possessions a game, the most in the competition, roughly twenty-five more per game than the next best side and thirty-two more than Sydney.

The idea was to break a zone from inside it. Rather than kicking over a defensive structure, the Bulldogs handballed through it in short bursts, using runners arriving at pace from behind the contest. Handball is faster than a kick to release and cannot be intercepted from twenty metres away, so a chain of three or four handballs can move the ball out of a stoppage before the zone shifts.

The cost is that a dropped handball at the bottom of a pack is a turnover in the worst possible place. The style requires very clean hands under pressure and a lot of players willing to run into contact, which is why it has never become universal.

Forward-half pressure: Richmond 2017

Richmond's 2017 premiership under Damien Hardwick was built on a principle that now underpins most AFL game plans: the most valuable ball in football is a turnover won in your own forward half, because it produces a scoring shot at a far higher rate than a clearance does.

The structure was unusual. Richmond played a single genuine marking target with a forward line of small, fast, relentlessly chasing players around him. That arrangement came about partly by accident and became the club's defining asset. Rather than trying to mark the ball inside fifty, the forwards were there to make sure the opposition could not get it out cleanly.

Hardwick was named the AFL Coaches Association coach of the year for 2017. What the style proved was that a forward line does not need four tall targets if it can generate enough repeat entries. Almost every club has since carried at least two designated pressure forwards, and tackles inside fifty became a headline statistic on the broadcast.

The corridor versus the boundary

Every ball movement decision in Australian football is a version of the same trade-off. The corridor, the strip through the middle roughly the width of the centre square, is the shortest route to goal. It is also the place where a turnover is most punishing, because the opposition receives the ball with a straight run at an undefended goal.

The boundary is safe and slow. A kick down the line goes to a contest, usually results in a stoppage or a throw-in, and gives your own defence time to set. Sides protecting a lead default to the boundary. Sides chasing a game go through the middle.

The best modern teams do not choose one. They use the boundary to move the ball into a position where the corridor becomes low risk, typically by switching to the opposite side of the ground and attacking a defensive zone that has slid too far. The moment a defensive structure is out of shape is the moment the corridor opens, which is why so much of a modern game plan is about manufacturing that half-second.

How teams switch play and why it is dangerous

A switch is a kick across the ground, usually behind the ball, to a teammate on the opposite flank. It is the single most reliable way to break a rolling zone, because a zone that has slid to one side of the oval cannot reset instantly.

It is also the kick most likely to end a coach's afternoon. A switch travels laterally in front of your own goal. If it is intercepted, the opposition has possession forty metres out with the defence facing the wrong way. Coaches therefore set strict conditions on when a switch is allowed: a clear target, a certain distance from goal, no immediate pressure on the kicker.

The 2021 stand rule made switching considerably easier, because the player on the mark can no longer move sideways to cut off the angle once the umpire has called stand. That change did more to open up ball movement than most of the rules that were introduced specifically for the purpose.

The kick-in as a scoring source

The kick-in after a behind is the most controlled restart in the game and clubs treat it as a set play. The traditional response was the huddle, where a group of players bunched at the top of the fifty and then broke in different directions, giving the kicker a designated first option.

Modern kick-ins are faster. Since 2019 the player has been able to play on without kicking to himself, and the arc has been marked so defenders must stay outside it. From 2026 the time allowed has been standardised at eight seconds, cut from roughly twelve, across about twenty-one kick-ins a match.

The offensive value is real. A team that can move the ball from a kick-in to a scoring shot in three or four disposals is attacking a defensive structure that has not yet reset. The defensive value is equally real, which is why forward lines now set a zone at the kick-in rather than trotting back to their opponents. Supporters at grounds sometimes call the result of stealing a kick-in and goaling a seven-point play, since the behind and the resulting goal represent a seven-point swing.

Rule changes as tactical intervention

The AFL has a long record of legislating against successful defensive tactics, which is unusual among major sporting bodies and reflects the league's commercial interest in a high-scoring, free-flowing product.

The pattern repeats. A coach finds a structure that suppresses scoring. Other clubs copy it. Scoring falls, the football public complains, and the league's competition committee introduces a rule aimed at the structure. The rule works for a season or two, coaches adapt, and a new structure emerges. Deliberate out of bounds, the deliberate rushed behind, the protected area, the kick-in changes, 6-6-6 and the stand rule all belong to this cycle.

Whether it works is genuinely contested. Long-running analysis of the interchange cap found that congestion metrics moved in the opposite direction to what the AFL predicted, which is the subject of the companion page on interchange rotations.

6-6-6 and what it actually changed

The 6-6-6 rule arrived in 2019. At the start of each quarter and after every goal, each side must have six players inside its defensive fifty, six inside its forward fifty, four in the centre square and one on each wing. Teams have about forty seconds to get into position. The AFL's football operations manager at the time, Steve Hocking, framed the package as an attempt to create more free-flowing passages of play and more one-on-one contests.

It did what it was designed to do at the centre bounce. A centre clearance now begins with a guaranteed clean structure and there is a genuine one-on-one for the first few seconds. It also made the ruck contest more important, because the side that wins the tap gets a rare uncontested look.

What it did not do was touch the rest of the ground. Throw-ins and around-the-ground ball-ups have no positional requirement, and those are where most congestion sits. Anyone expecting 6-6-6 to open the game up broadly was disappointed, which is roughly the AFL's experience with most congestion rules.

The stand rule and ball movement

Introduced for 2021, the stand rule requires the player on the mark to freeze the moment the umpire calls stand. Any movement, even a step sideways, is a fifty-metre penalty. Players within five metres of the mark must stand rather than retreat.

This was a bigger tactical change than it looked. Under the old rule the man on the mark could shuffle across to shepherd the kicker towards the boundary, which meant a switch could be shut down by one player. Removing that made the diagonal kick available from every mark, which is precisely the kick that breaks a zone.

The rule was unpopular with some past players when introduced, partly because the fifty-metre penalties looked severe for tiny infringements. It has stayed. For 2026 the AFL tightened enforcement again, requiring players near the mark to stand rather than drifting back to a position outside five metres, on the reasoning that drifting back was quietly reintroducing the old shepherding effect.

What the 2026 rule package does to game style

Seven changes came in for 2026 and several of them have tactical consequences.

The centre bounce was abolished from round one and replaced with an umpire throw-up, ending a practice that dated to 1887. Rucks may no longer cross the centre line before engaging, an attempt to restore genuine jumping contests, which the AFL reported had fallen from about 63 per cent of centre contests in 2023 to about 21 per cent in 2025. The requirement for a player to start in the goal square after a goal was removed, saving roughly twenty to thirty seconds a match.

The most tactically significant is the last disposal rule. A free kick is now paid against the player who last disposed of the ball before it crosses the boundary between the arcs, replacing the old insufficient intent judgement. That removes a defensive escape hatch. A defender under pressure can no longer bank on a throw-in from a hurried kick to the boundary, which should reduce boundary-line stoppages and push more sides to keep the ball in play.

Where the tactical trend sits now

Recent seasons have pushed in a few consistent directions. Midfield structures have moved from a triangle around the contest towards a diamond, with an extra body positioned ahead of the ball, which several analysts have associated with Geelong and Brisbane. Half-back lines have become interchangeable, with defenders rotating between intercept marking and ground-level defence so that opposition forwards cannot settle on a match-up.

Fremantle has been among the sides most identified with an aggressive rolling zone and aggressive half-back interceptors, and has held some of the lowest opposition scoring averages in the competition as a result. Collingwood's identity has been forward-half pressure and repeat entries. Brisbane won the flag in both 2024 and 2025, taking the 2025 Grand Final 18.14 (122) to 11.9 (75), and its style rewards a deep, even midfield rather than a single dominant ball winner.

Interchange management has itself become tactical, with clubs using bursts of rotations to attack a momentum swing rather than spreading changes evenly, a subject covered on the interchange page.

AFL tactics explained on the couch: what to watch

If you want to read a game style live rather than wait for the post-match analysis, watch four things.

Watch where the ball goes from a defensive fifty mark. Sideways and backwards means a possession game. Long down the line means the side is protecting territory or has been told the corridor is off limits. Straight through the middle means a team is either confident or desperate.

Watch the forwards when the opposition has the ball at half-back. If they are running towards their own goal, the side is defending with numbers. If they are running at the ball carrier, the side is pressing.

Watch the centre bounce set-up now that 6-6-6 applies, and count how quickly the structure dissolves. Within ten seconds the four players in the square will usually have become eight around the ball.

And watch what happens after a behind. The kick-in is the clearest window into a club's ball-movement rules, because it is the one moment where the team has full control and eight seconds to use it.

Terms you will hear on the broadcast

A few pieces of vocabulary make the commentary easier to follow. A one-percenter is any act that does not appear in the possession count: a smother, a shepherd, a spoil, a knock-on. Chaos ball is a deliberately hurried long kick into a crowded forward fifty, used when a side cannot generate a clean entry. Tempo is a possession chain designed to slow the game rather than advance it.

An intercept is a mark or possession taken from an opposition disposal, and intercept marks inside defensive fifty are one of the most tracked figures in the modern game. The hole is the space directly in front of a full-forward, occupied by a spare defender. A run-with player is a midfielder assigned to an opponent rather than to the ball, the modern and more mobile version of the old tagger.
