Round 18 Preview — 2026 NRL SeasonNRL Analytics

Knights v Dolphins

Knights 5-0 H2H — longest active streak in the matchup. Dolphins DS 18.3 but remaining squad still +7.8. Lean tip: Knights by 6.

SavvyPlays · 2 July 2026 · McDonald Jones Stadium, Newcastle · Sunday 5 July · 4:05PM AEST

The Dolphins name a Disruption Score of 18.3 — the highest of the round. Hamiso Tabuai-Fidow, Isaiya Katoa, Tom Flegler, Kurt Donoghoe rotations, and Jack Bostock all unavailable in one week. That is a lot of quality to lose. And yet — the remaining Dolphins starting 13 still averages +7.8 ±/G, higher than the Knights' starting 13 (+2.4). The depth is extraordinary.

The counter-signals for the Knights: 5-0 H2H over the last five meetings — the longest active streak in this exact matchup — a 33% Dolphins win rate at McDonald Jones historically, and a CI/DS edge of +7.6 to the home side. The model says Dolphins -9.2, but H2H + venue + CI/DS all point the other way. Lean Knights by 6 — a genuine model-override tip.

SavvyPlays Tip — Lean

01Knights by 6

Three signals push the tip toward the Knights against the model. First, the H2H: Knights 5-0 over the last five meetings, the longest active streak in this exact fixture. Every meeting since R3 2023 has gone the Knights' way, including a 26-20 win at HBF Park in R16 2025 and a 26-12 result here at McDonald Jones in R2 2025.

Second, the venue: the Dolphins have won 33% of their visits to McDonald Jones. Third, the CI/DS edge: +7.6 to the Knights. The Dolphins name a Disruption Score of 18.3 — the largest of the round — with Tabuai-Fidow, Katoa, Flegler and Bostock all missing.

The counter is real. The model still has Dolphins -9.2 because their remaining starting 13 averages +7.8 ±/G — better than the Knights' +2.4. That is why this is Lean, not Strong. The Dolphins have exceptional depth. But H2H, venue and CI/DS combine to override the model call.

Venue & Head-to-Head

02Venue & Head-to-Head

Match Analysis

05Key Matchups & Narratives

Dolphins depth is extraordinary. DS 18.3 with Tabuai-Fidow, Katoa, Flegler, Bostock and rotations all out — and the remaining 13 still averages +7.8 ±/G. Herbie Farnworth (+8.8), Jamayne Isaako (+8.7), Connelly Lemuelu (+8.3) and Jeremy Marshall-King (+20.3 in a small sample) still start. This is why the model has them favoured despite the disruption.

Knights spine intact. Fletcher Sharpe (+3.4) at fullback, Dylan Brown (+4.9) at halfback, Sandon Smith at five-eighth, Phoenix Crossland at hooker. Dylan Lucas (+6.7) and Mat Croker (+3.7) provide reliable middle-forward output. Starters average +2.4 ±/G.

The venue lever matters here. McDonald Jones has been a genuine headache for the Dolphins — 33% win rate. Two of the five straight Knights H2H wins came at this venue (R2 2025, R27 2024) by scores of 26-12 and 14-6. The Knights have a genuine tactical advantage on this ground.

CI/DS +7.6 to the Knights. Consistency and disruption both favour the home side heavily this week. That is the primary reason we override the model call — the Dolphins are less predictable at 18.3 DS and the Knights are more consistent to boot. Lean Knights by 6.

Knights 5-0 H2H — Longest Active Streak

The Knights have won five straight against the Dolphins dating back to R23 2023. Two of the five wins came at McDonald Jones. The venue lever, the H2H streak and the CI/DS edge together are what push this tip to Knights despite the model favouring the Dolphins.

Model Override

This is a genuine model-override tip. Predict margin -9.2 with the Dolphins favoured, but the SavvyPlays call is Knights by 6. The confidence is Lean specifically because the Dolphins retain +7.8 ±/G on their remaining starters. Their depth is real.

Prediction

06Prediction Breakdown

Model reads Dolphins -9.2. We override to Knights by 6. Three factors drive the override: the 5-0 H2H (longest active streak in the fixture), the Dolphins' 33% record at McDonald Jones, and the CI/DS edge of +7.6 to the home side. The Dolphins' +7.8 remaining squad ±/G is why this stays a Lean rather than a Strong tip. Knights by 6.
