How to manage a rugby roster that survives mid-season

Most coaches learn how to manage a rugby roster the hard way: game 1, key player down, the depth chart you sketched on Wednesday turns into musical chairs on the touchline. It happens every season. The realization, every time, is the same — the system you thought you had wasn’t really a system.

This post is the roster schema I use now. Two layers: a primary position for every player, and a set of position bands that say who can flex where. It survives mid-season injuries because the gaps are mapped before the gap appears. It works on paper, in a spreadsheet, or in SetPiece — whatever you’ll actually open on a Saturday.

Why your depth chart breaks mid-season

The high-stake losses are where your key-players usually live: front-row, 8, flyhalf, scrumhalf. Someone goes down and you’re scrambling on the touchline, playing musical chairs with the lineup and the bench rotation. The other twelve guys can be the best squad you’ve ever had — lose one of those four and the next forty minutes get loud.

This past season our new flyhalf took 90% of practice reps through preseason. Game 1: season-ending injury. Cue the chaos! I had no idea who to move where, or how, or when. The session plan I’d built around him was fine; the roster I’d built around him wasn’t. An hour into the season and I was already making it up.

That’s when I realized my system was broken. Whatever I thought I had — a depth chart in a notebook, a few “he could probably cover” mental notes — it wasn’t a system. It was broken, and it failed immediately. Apparently hopes don’t always survive game 1.

Primary position: one per player, no exceptions

Every player gets one primary position. Not three. Not “wherever I need him.” One. The rule for picking it is simple: a player thrives where their natural skillset is a strength and the role fits your shape. Both halves matter.

The way to find it before the season starts is to do the work in reverse. Go through each position, one by one, and write down the perfect player for that spot. Their skills. Their personality. How they show up to training each week. Physical attributes. Fitness.

Here’s my dream 8: dominant runner, skilled short-pass, comfortable in contact, knack for making the offload. Observant, leads by example. Physicality gets them into trouble more than their mouth does.

Once you’ve got fifteen of those written down, the selection process is self-evident. You’re not picking a player and trying to fit them somewhere — you’re holding a shape in your head and matching faces to it. With this method I’ve been able to confidently assign primary positions in the first week or two of preseason, with minimal adjustments after.

And when the flyhalf goes down in game 1, you know what you’ve just lost. You also know what it takes to fill the gap.

Position bands: where the depth actually lives

Position bands are how your roster survives the season — and mid-game tragedy. Here’s the common breakdown:

• Front-row (1–3)
• Second-row (4, 5)
• Back-row / loose forwards (6–8)
• Forwards (1–8)
• Half-backs (9, 10)
• Centers (12, 13)
• Back-three (11, 14, 15)
• Backs (9–15)

I also add a few of my own: tight-five (1–5) for the big boys, loose-five (4–8) for flexibility or developmental players who aren’t quite front-row forwards yet, and tacticians (9, 10, 15) for the decision-makers.

Once the bands are defined, start tagging your roster. Each player gets their primary position, then any bands where that position falls — smallest to largest — but only if you’re comfortable with them flexing there. A primary 8 gets back-row and then loose-five.

If your 8 also has the hands to run in the centers and that’s your preferred emergency fallback, add the centers band on top. The band doesn’t have to be the natural cluster — it has to be the truth about what you’d actually do in the 28th minute.

Filling a gap when the season throws one at you

With the band system in place, replacing the flyhalf mid-game becomes a simple series of checks instead of a panic.

First look at the bench sheet. Anyone with 10 as primary or tacticians in their bands? That’s your direct slot. Bring them on.

If there’s nobody on the bench who fits, look at the pitch. Who’s currently playing a position you can flex to 10 — and crucially, who has a strong bench replacement for the spot they’d leave? A primary 15 with tacticians on their card and a fresh 15 on the bench is your move. A primary 12 with tacticians but no real 12 cover on the bench is a trap; you’re just digging a different hole.

Two checks. Maybe twenty seconds. Trust your system. Then trust your gut on the close calls.

After the game, revisit. Was the gap obvious in hindsight? Should anyone earn a new band based on how they handled the cover role? Should someone lose one? The roster isn’t a thing you set in preseason — it’s a thing you keep current.

How to run it — paper, spreadsheet, or app

I’ve done this on paper, in a spreadsheet, and in SetPiece. They all work. Use whatever’s easiest and most habit-forming for you.

Paper cements the mental notes — writing each player’s bands by hand makes the cover options stick in your head, which is half the point. It gets cumbersome on the sideline, though, when a folded sheet in your back pocket meets the third squall of the afternoon.

A spreadsheet makes band management easy: drop-downs for primary position, multi-select cells for bands, sort and filter to find who fits where. The cost shows up on Saturday. A grid built for a 24” monitor turns into a panicked pinch-zoom on a 6” phone, and you lose ten seconds finding the right row while the gap widens.

SetPiece runs the checks for you. When the flyhalf goes down, it shows you the bench options first (10 primary, then tacticians), then the pitch flex options with their bench cover already evaluated. Right on your phone, in the rain, between whistles.

Pick the medium you’ll actually use every week. The schema is what matters; the tool is whatever stops you from making it up again.
