Roosters vs Dolphins NRL head-to-head tips, prediction and value bets

Intro

The Roosters enter Round 26 at 16-6 against a Dolphins side sitting 15-7, so there is little room for passengers in this matchup. Sydney have the better overall record, while the Dolphins arrive with five consecutive wins. The betting question is whether those advantages justify the gap in the market when the Dolphins have been rolling through opponents with huge yardage and consistent attacking pressure.

The best price for Roosters is $1.58 with Sportsbet, offering 1.7% better return than the average market price. The best price for Dolphins is $2.50 with PointsBet, offering 2.1% better return than the average market price.

Recent Form

The Roosters have won four of their past five, although their latest outing ended in a 25-24 loss to Tigers. They have scored 32.2 points per game over that stretch, well above the league mean of 24.4, but Round 22 against the Cowboys produced a huge 82-point outlier. From earliest to most recent, their scores were 23, 82, 20, 12 and 24. Their 80.4% completion rate also compares favourably with the Dolphins at 75.6%, giving Sydney the cleaner recent foundation with the ball. The Roosters have done this work against the stronger recent schedule, which adds weight to their 16-6 season record.

Margin

Margin combines scoring and defence into one number and anchors the recent form story.

Completion rate

Sydney's 80.4% completion rate compares with the Dolphins at 75.6% and highlights a meaningful difference in recent ball control.

The Dolphins are 15-7 and have won their past five, beating the Cowboys, Dragons, Broncos, Sea Eagles and Eels in succession. They have scored 32 points per game across that run without a scoring outlier comparable to Sydney's 82 against North Queensland. Their defence has conceded 17.2 points per game, while opponents have completed at just 76.2%, comfortably below the league mean of 79.6%. The qualification is the opposition they have faced recently has been weaker overall than Sydney's, so their winning run deserves some tempering when assessing this step up.

Strengths & Weaknesses

The Dolphins' clearest strength is their ability to keep travelling through contact. They have generated 1901.8 run metres per game over the past five, around 237 metres more than the league mean of 1664.7, while their 616.8 post contact metres sit about 72 metres above the league average of 544.5. That territorial power has helped produce 7.8 line breaks per game against a league mean of 5.7. The catch is ball security. The Dolphins make 13 errors per game compared with the Roosters' 11.4, so Sydney are the cleaner side on the raw numbers.

Opponent line breaks

Both teams have restricted opponents to 4 line breaks per game, making resistance to attacking pressure a shared strength.

Sydney's strongest answer is defensive resistance. The Roosters have allowed only 4 opposition line breaks per game and the Dolphins have also conceded 4, so that strength largely cancels out. Sydney have missed 27.8 tackles per game compared with the Dolphins' even better 25.2, with both comfortably below the league mean of 33.4. The Roosters have also held opponents to a 74.6% completion rate compared with 76.2% for the Dolphins. The visitors have another defensive strength in shutting down second phase play, restricting opponents to 6 offloads per game against a league mean of 9.1.

Missed tackles

The Roosters have missed 27.8 tackles per game and the Dolphins 25.2, with both defending strongly by league standards.

Key Players

Sydney's attacking threats are spread through their outside backs and spine. Billy Smith has scored 1.2 tries per game across his past five appearances while producing 1.4 line breaks per game over the same span. Sam Walker has supplied 2.4 line break assists and 1.8 try assists per game across his last five, although both creative numbers have cooled recently. James Tedesco returns this week after producing 1 try assist per game across his past five appearances, rising to 1.3 over his most recent three. Victor Radley is out this week after contributing 0.4 line break assists per game across his past five appearances.

Sam Walker — Line break assists

Walker's 2.4 line break assists per game across his last five quantify his central role in Sydney's recent attacking creation. The league average is based on players in the same position and is calculated using recent performance data across the competition.

The Dolphins have enormous recent production through their outside backs. Herbie Farnworth has generated 183 run metres per game across his past five appearances and that has climbed to 196.3 over his most recent three, alongside 6.4 tackle busts per game across the longer window. Selwyn Cobbo has scored 1 try per game and produced 1.6 line breaks per game across his last five. Jamayne Isaako adds another finishing threat with 1.2 tries and 1.2 line breaks per game across his past five appearances. Hamiso Tabuai-Fidow has supplied 196.8 run metres per game across his last five, giving the Dolphins several ways to turn their territorial strength into attacking pressure.

Herbie Farnworth — Run metres

Farnworth's 183 run metres per game across his past five are a major component of the Dolphins' broader territorial strength. The league average is based on players in the same position and is calculated using recent performance data across the competition.

Tactical Outlook

The Dolphins should want a territorial contest and repeated opportunities to carry at Sydney's defensive line. Their 44.7 metre average set distance is more than four metres above the league mean of 40.6, and it fits naturally with their huge run metre and post contact output. Sydney's defence is the wall they have to crack. Both teams have restricted opponents to 4 line breaks per game, so clean attacking chances may be harder to manufacture than their scoring averages suggest. Ball control could become decisive because the Dolphins' 13 errors per game exceed Sydney's 11.4. If the visitors repeatedly surrender possession, their yardage advantage can disappear quickly.

Errors

Sydney's 11.4 errors per game compare favourably with the Dolphins' 13 and could influence possession in a tight contest.

Prediction & Value Bet

We still rate the Roosters as the more likely winner. Their 16-6 season record, home setting, strong defensive numbers and the fact they have faced the tougher recent opposition give Sydney a narrow overall advantage. We make the Roosters a 58% chance and the Dolphins a 42% chance. The Roosters are $1.55 favourites with a market-implied probability of 64.4%. That demands considerably more certainty than our assessment supports. The Dolphins are $2.45 outsiders with a market-implied probability of 40.8%. Our 42% assessment gives them a slightly greater chance of an upset than the market is implying. The difference is modest, but our recommendation is Dolphins head to head at $2.45.
