Offense Against a 1-3-1 Zone: A Box Lacrosse Approach

If your box coach calls a defense “1-3-1,” confirm the assignments before choosing an offense. Against the shape described below, try a low feed and one timed inside cut, then read which defender moves. Don’t force a pass through the middle simply because the formation looks open on a diagram.

In basketball, a 1-3-1 has one defender high, three across the middle and one covering the baseline area. That is the setup described in this basketball coaching guide. Its court positions and corner traps are not a box lacrosse playbook.

Here, the proposed box shape means one high defender, two middle wings plus a central defender, and one low defender near the crease. The approach below is a suggested attack against those assignments—not a universal box system attached to the label.

Start balanced, then move the defense

Use five attacking positions:

• One point: high in the middle, available to move the ball from side to side.
• Two shooters: one on each side, above the low players.
• Two low players: one on each side of the goal, outside the crease.

Leave enough separation that one defender cannot pressure two receivers without moving. Where possible, position players so their stick heads face the middle rather than the boards.

These are established box-offense fundamentals: the Canadian Lacrosse Association’s 2004 coaching progression introduces floor balance, sticks toward the centre, give-and-go play and creating space off the ball. Apply those principles to the defense in front of you.

Run a low feed and a timed cut

Try this sequence first at walkthrough speed:

1. Point passes to a shooter. The receiver catches ready to shoot or pass, rather than turning immediately toward the boards.
2. Shooter passes to the low teammate on that side. Keep the point available as a return outlet. If the defense denies the low pass, swing through the point and try the other side rather than forcing it.
3. The opposite shooter cuts toward the goal through an available inside lane, staying outside the crease. Start as the low receiver secures the ball—not so early that the cutter arrives before the passer can look up.
4. The opposite low player lifts into the vacated shooter position. If the cutter receives no pass, they clear the middle and fill the low spot.

Getting the ball low and then looking for an opposite-side shooter cut is part of the motion sequence in Box Lacrosse Basic Systems. This is a simplified adaptation that keeps the point as an outlet. Use it to test how the central and low defenders share responsibility.

Checkpoint: the cutter should arrive with a visible stick target while the passer has control and a clear view. If two attackers occupy the same lane, reset the spacing before adding speed.

Read the defender, not the planned pass

The low receiver has three useful decisions:

Defensive cue	Attacking response
The cutter separates and the passing lane is clear	Feed into the cutter’s path for a catch-and-finish opportunity.
The lone low defender steps toward the ball while the central defender covers the cut	Check the far-side low player during their lift. Feed only if both the receiver and the lane are open.
The middle collapses and sticks block the feed	Return the ball to the shooter or point and move it to the other side.

The key question for this shape is: when the low defender moves toward one side, who covers the other? Watch whether a middle defender drops to help; don’t assume that the far side is unguarded.

An open teammate is not enough: the lane to their stick must also be open. Avoid floating a diagonal pass across several defenders. Use the high outlet when the direct route is blocked.

If the defense stays compact, don’t answer with repeated cuts into traffic. Let the first cutter clear before looking again. If there are actually two low defenders and one point defender, use the house-zone explanation to clarify the coverage instead.

Practise the decision in three stages

Use five attackers, five defenders and a trained goalie under a coach’s supervision, with all players wearing the required protective equipment.

• Walkthrough: defenders hold the agreed shape while attackers rehearse the low feed, cut and replacement.
• Guided defense: defenders may shift and intercept, without body contact. The offense chooses an inside feed or a return pass based on the lane.
• Live possessions: apply your competition’s shot clock and contact restrictions. End each repetition on a shot, turnover or clock expiry.

After each possession, ask: “Which defender moved, and what became available?” A sound decision may be a safe return pass rather than an inside feed. Reward recognizing that difference—not merely completing the rehearsed sequence.
