Who Can Your Team Least Afford to Lose?

Around the midpoint of the season we published our first player plus/minus analysis, a capability we believe remains unique to SavvyPlays. With Adam Doueihi dominating the footy headlines this week, it felt like the right time to quantify his value to the Tigers relative to his teammates, and while we were at it, to refresh the analysis for every club.

Basketball fans have argued about plus/minus for two decades. The idea is simple: track the scoreboard while each player is on the floor. If your team outscores the opposition by 8 points during your minutes, you're +8, regardless of whether you scored a single point yourself.

Rugby league has largely gone without it. Official statistics count what a player does: runs, metres, tackles, tries. They've never systematically counted what happens while a player is on the field. Using play-by-play timeline data, we reconstruct every player's exact on-field stints, covering every interchange, sin bin and minute played, and measure the scoring margin during those windows. Averaged per game, that's ±/G.

One rule before you read on: plus/minus is a within-team metric. A middle-of-the-road Panther will out-rate a good Titan, because the Panthers out-rate the Titans. The interesting comparisons are between teammates: who lifts their side relative to the players around them, and whose minutes coincide with the tide going out. Keep that in mind throughout.

The highest ±/G at each club among players with 10 or more games. Some names you'd expect. Several you wouldn't.

Three clubs (the Broncos, Dragons and Eels) don't have a single 10-game player in positive territory. Their "most valuable player" is simply the one who loses the slowest. At the other end, the Panthers' best is nearly six points per game clear of any other club's best. More on both below.

Casey McLean is having the quietest monster season in the NRL.

Not Cleary (+16.6). Not To'o (+17.7). Not Edwards (+16.4). The best plus/minus at the best club belongs to Casey McLean at +19.4. When he's on the field, the Panthers win his minutes by nearly three converted tries per game. The Panthers own the seven best ±/G figures in the competition outright, which tells you plenty about the machine, but McLean topping that list ahead of the game's biggest names is the kind of signal traditional stats never surface.

The Storm run hot and cold, and the roster explains why.

The widest gap between any club's best and worst qualifier belongs to Melbourne: Ativalu Lisati at +13.6, Alec MacDonald at -4.9, an 18.5-point internal spread, with the Tigers (17.8) close behind. For a club whose consistency index has ranked among the league's most volatile all season, this is the player-level explanation. The Storm rotation contains both genuinely elite minutes and genuinely losing ones, and which version takes the field goes a long way to deciding their night.

The marquee misfires.

Two of the most uncomfortable numbers in the dataset belong to two of the most discussed players in the game. Mitchell Moses (-13.1) is not just struggling. He is statistically the worst 10-game player on the Eels' roster, and the scoreboard bleeds fastest when the franchise halfback is on the field. Injuries, a broken team around him and the constant halves churn all contribute, but the number is the number.

Jarome Luai (-15.3) tells a similar story at the Tigers. The premiership-winning five-eighth's minutes coincide with a 15-point-per-game deficit, the worst figure of any Tigers qualifier. His R18 absence, when the Tigers' data actually improved without him, was flagged in our preview analysis at the time. Marquee recruitment is about more than one player's talent; these numbers show how heavily context weighs on even elite footballers.

The Doueihi datapoint.

No player gives this article's question a sharper edge than Adam Doueihi, who made headlines by standing down from the Tigers' Round 21 fixture amid a dispute over being selected out of position. Set the politics aside and look at the number: Doueihi's -0.2 across 12 games makes him one of just three Tigers qualifiers whose minutes hold the scoreboard essentially level, and comfortably the best of the club's halves options. On a roster where the alternatives in the halves run from Madden (-9.3) to Luai (-15.3), break-even is elite. The game he sat out? The Tigers lost 56-10. One match proves nothing on its own, but the season-long data and the scoreboard that weekend are telling the same story: whatever position he plays, Doueihi is one of the few players the Tigers genuinely cannot afford to leave on the sideline.

Ponga is the classic case study.

Kalyn Ponga (+8.6) returned from injury and instantly became the Knights' best player by this metric, on a team whose next-best qualifier sits at +5.4. The eye test, the market and the plus/minus all agree here, which is exactly what you want from a new metric: when it confirms the obvious, you can trust it more when it surprises you.

The breakout signals.

The surprises are where plus/minus earns its keep. Ativalu Lisati (+13.6) leads the Storm, ahead of Munster (+0.3), Grant (+1.0) and Hughes (+2.5). Hugo Savala (+10.7) out-rates Tedesco, Walker and every Rooster with a representative jersey. Clayton Faulalo (+13.9) tops the Sea Eagles ahead of all three Trbojevic brothers and Luke Brooks. Young, cheap and scoreboard-positive, these are the players smart clubs build depth around, and the ones our match previews have been flagging in squad tables all season.

The spread between a club's best and worst qualifier reveals something league tables can't: whether a team's problem is its stars or its depth.

Note the shape at each end. The Panthers' worst qualifier is +5.4; their floor would be the ceiling at seven other clubs. The Warriors and Sharks are the only other clubs whose every qualifier is positive: three rosters with no passengers, and not coincidentally three of the top four. Meanwhile the Cowboys' 7.0-point spread is the league's tightest. No stars, no sinkholes, everyone within a converted try of each other. That evenness is exactly how a team with no top-20 player sits eighth and keeps breaking H2H streaks against fancied opposition.
