Overview

The Vertical Stack is our alternate offensive shape. Where the Spread Stack de-clutters the centre by pinning four cutters to the sideline, the Vert puts the cutters in a single line up the middle of the field and creates two clear lanes — open and break — on either side of the stack. One cutter peels off the back of the stack at a time and attacks one of the two lanes, with the rest of the stack acting as space and as the next-cutter queue.

We use Vert when we want a clearer single-cutter picture, when we want to attack the deep space directly, or when matchups make the side-stack hold harder than usual. Our give-and-go rhythm still runs out of Vert — handler exchanges happen in the same way; the cutting picture is just different.

Setup

• 2 Handlers — wide and balanced behind the disc, the same shape as in Spread
• A central stack of 4–5 cutters — vertical, single-file, lined up through the centre of the field, starting roughly 10–15m in front of the disc and extending downfield
• The stack is far enough infield that the Open Side and Break Side cutting lanes are both clearly defined

Why This Works

The Vert creates a single, unambiguous picture for the cutters and the throwers. Only one cutter is active at a time — the one peeling off the back of the stack. Their two options are clearly defined: open-side cut into the open lane, or break-side cut into the break lane. There is no third lane to confuse the picture.

For the defence, Vert produces a different problem from Spread. In Spread, the question is do we help in the middle? In Vert, the question is do we poach off the stack? — because every defender on the stack is standing in the middle of the field. A poach off the back of the stack can disrupt deep cuts; a poach off the front can disrupt unders. Either way, Vert demands defenders sit close to their marks, and that opens deep lanes for us to attack.

Vert is also the cleanest shape for handler Give-and-Go sequences, because the central handler space has nothing in it — the stack starts well downfield, leaving the entire handler set room to work.

Roles

The Handlers — Same as Spread

The handler set looks identical to Spread: Active Handler, Dump Handler, with a Secondary Handler sliding behind. The give-and-go work runs the same way.

The Active Cutter — Peel and Choose

One cutter is peeled off the back of the stack at any time. Their job is to read the Force and make the cut that punishes it: open-side under or away, or a break-side under against a defender who has cheated open-side. After the cut, they clear all the way through to the front of the stack, not into the same lane.

The Stack — Hold and Cycle

The remaining cutters hold a clean vertical line. They do not drift, do not bunch, and do not cut until they are at the back of the stack. The discipline is the same as in Side Stack — the value is what they are not doing.

The Last-Back — Deep Threat

The cutter at the very back of the stack is also our deep threat. When the disc moves into a position where a deep look is on (typically after a Swing or a clean leading pass), the last-back can break off and strike. See 4 Lines - Strike Cut and Expansive - Deep Game.

Triggers and Reads

• Defence pinches the stack → open-side under is on. The cutter peels and attacks under in stride.
• Defence overcommits to the open side → break-side under is on. See Vert Stack - Breakside Under.
• Defenders sit under and stop respecting the deep → trigger Expansive - Deep Game off the last-back.
• Defence tries to poach from the stack → the freed cutter must immediately become active. See Free Poaching and Make the Effort - Quick Ref for the inverse defensive principle.
• Disc moves laterally → the stack rotates with the disc, keeping its line through the centre of the new picture rather than the original one.

Common Errors

• Two cutters peeling at once. The single-cutter discipline is what makes Vert work. Two cutters from the stack at the same time produce the same congestion problem Spread is built to avoid. Reinforce: only the back of the stack cuts.
• Cutting from the wrong end. Front cutters who peel off without waiting their turn break the rotation. Stack cuts come from the back.
• Stack drifting infield. A stack that is not vertical is just congestion in the middle of the field. Hold the line.
• Clearing back into the cutting lane. A cleared cutter who drifts back into the lane they just cut from blocks the next cut. Clear all the way to the front of the stack.
• Handlers crowding the stack. Handlers should stay behind the disc and let the stack live downfield. A handler drifting up into the stack collapses the picture.
