Also, even in zone defence, some opponents, for example those moving into dangerous space, may temporarily need to be marked.

In principle, there are two ways of defending, zone defence and man-to-man defense.

Zone defence does not require a sweeper role, and as many teams have changed their tactics to this, sweepers are today rare.

Over the pre-season Lyon worked on a new game plan based around forward pressure, midfield zone defence and pushing numbers behind the ball.

Each defender (including the left winger) plays a zone defence and is responsible for a third of the ice each.

The Gades tend to use a man-to-man defense, although have been known to switch to zone defence positions on occasion.

The zone defence at kick ins was popularised by Kevin Sheedy and brought from basketball.

The zone defence tactic, borrowed from basketball, was introduced into Australian football in the late 1980s by Robert Walls and revolutionized the game.

While the role of first and second defenders are rather similar, the third defenders' role is very different in zone defence and man-to-man defence.

In practice, however, every defence will be a mix of zone defence and a man-to-man defence, although often with heavy leanings towards one or the other.

The rolling zone or cluster, poineered by Hawthorn coach Alastair Clarkson executes the zone defence, but across the entire field.

In a zone defence, defensive players mainly move in relation to each other, whereas a man-to-man defence mainly moves in relation to opposing players.

This allowed the actual systems to have the characteristic of being specialised either in short-to-medium range "point defence" (ships, for instance), or in medium-to-long range "zone defence" (fleets).

At corner kicks, and at direct free kick, indirect free kick or throw-ins that are likely to become a cross, most teams use man-on-man marking, even those which otherwise play zone defence.

Squeeze: a type of zone defence used to force attacking players to move the ball to the wings to gain and/or take advantage of an overlap (by which time the defence should have had time to re-position itself).

In zone defence, second and third defenders and midfielders are organised in two lines, in the transverse direction of the field, thus organising a defender line and a midfielder line, the midfielder line working as an "outer shield" for the defenders.
