Friday night footy under the Suncorp lights — and it's a Finals Week 3 clash that's got everything a punter could ask for. The Dolphins welcome the Sydney Roosters at 7:50 pm AEST on 25 September, and the form lines tell a tale of two very different runs into this elimination final.
The Dolphins arrive on a five-game winning streak, having rattled off victories over Manly, Parramatta, the Roosters themselves, Gold Coast, and the Warriors. That streak includes four away wins in their last five, and they've averaged 26.4 points for and conceded just 12.8 across that sample — a 13.6-point average winning margin that speaks to genuine momentum.
The Roosters, meanwhile, are coming off a 46–10 demolition of Cronulla last start, but that win came sandwiched between three consecutive losses — including a 12–26 defeat to these same Dolphins back on 29 August. Their last-five average sits at 22 points for and 31 against, with an average loss margin of 20.3 when they've gone down. The market has taken notice: the Roosters have firmed from 2.2 into 2.04, while the Dolphins have drifted slightly from 1.68 to 1.71.
Who takes it at Suncorp?
The Dolphins sit third on the ladder with 17 wins from 24 games, while the Roosters are fourth with 16 wins. But it's the trajectory that matters here — the Dolphins have won five straight, and the Roosters' season form of WLLLL tells you they've been hit-and-miss.
When these two met in late August, it was at the Roosters' home ground, and the Dolphins won 26–12. Go back to their June meeting and the Dolphins put 48 on the board against the Roosters' 10. The head-to-head average across those two matches sits at 48 total points, and the Dolphins have won both comfortably.
The Dolphins' home record this year is 8 wins from 12 games at Suncorp, and their only home appearance in the last five was a 34–16 win over Parramatta. The Roosters are 8–4 away from home, but their away form in the last five includes losses to Penrith and South Sydney (twice, by 30 points each time). That 46–10 win over Cronulla last start was at home, so they're yet to prove they can match the Dolphins' intensity on the road in this finals series.
The Dolphins' odds have drifted slightly to 1.71, while the Roosters have firmed to 2.04. That firming suggests punters are seeing value in the visitors, but the weight of recent evidence — five wins on the trot, a dominant head-to-head ledger, and home advantage — keeps the Dolphins as favourites. It's a tough ask for the Roosters to overturn that form line, even with their own last-start boilover.

Head-to-head context
Season and last-five scoring — context for the match-winner market.
Can the Roosters cover the line?
The line market has the Dolphins laying 2.5 points at 1.9, with the Roosters getting the same start at 1.9. That's a tight spread, and it reflects the market's belief this could be closer than the head-to-head odds suggest.
The Dolphins' average winning margin across their last five is 13.6 points, which comfortably covers the 2.5-point line. But dig into the individual results and you'll see margins of 22, 18, 14, 4, and 10 — so they've been putting sides away, but not every win has been a blowout. The Roosters' average loss margin of 20.3 in their last-five defeats would see them well outside the line, but their 36-point win over Cronulla shows they can still produce big numbers when it clicks.
The head-to-head history has the Dolphins winning by 14 points in August and 38 points in June. If the Roosters can replicate their Cronulla performance, they'll be competitive. But the Dolphins' consistency — five wins in a row, all by double digits bar one — makes the case that they'll win and cover again. The 2.5-point line feels generous given the form gap, and our nrl predictions lean toward the home side laying the start.

The betting verdict
The Dolphins have the form, the venue, and the head-to-head dominance. The Roosters have firmed on the back of one big win, but their broader form line — three losses in four before that Cronulla game — doesn't inspire confidence on the road in a finals environment. The line at 2.5 points looks short enough to trust the home side to cover, and the match-winner market at 1.71 still holds value if you're happy to back the favourites outright.
It's Friday night footy, it's finals, and it's the Dolphins at home with a five-game winning streak behind them. The Roosters will need to find a level they haven't consistently shown in recent weeks to upset this one.
