Roosters vs Dolphins Betting Edge

The bookies are just shading the Roosters as favourites with a 51.17% chance, but our deeper dive tells a different story, we’ve got the Dolphins with a solid 54.63% edge to take this one.

At the odds of $1.95, the Dolphins are offering genuine value. If our analysis is on point, there’s a small but clear opportunity to back the Dolphins and come out ahead in the long run.

Quick Match Stats Snapshot

The Dolphins are sitting a bit prettier at 9th in the power rankings, compared to the Roosters who are down in 14th, a 5-place gap that’s not massive, but certainly notable.

When we dig a bit deeper, the Dolphins have played slightly tougher opponents on average (8.13 average opponent rank vs the Roosters’ 11.38), and they’ve still kept their defensive numbers stronger. That suggests the Dolphins have been better tested and still holding their own.

Power Rankings Breakdown

What to do?

Interestingly, in this Roosters vs Dolphins matchup the Roosters have the edge when it comes to highest scores (hitting 46 points in a match compared to the Dolphins’ 42), but when it comes to consistency, the Dolphins record tips things in their favour. Plus, their True Power Score (weighted) of 7.20 absolutely smashes the Roosters’ 13.20 (lower is better here), giving even more reason to lean towards the Dolphins.

All up, while the bookies have this basically even money, our stats point to the Dolphins as the stronger side overall. Backing the Dolphins at $1.95 looks like a solid shout based on the numbers!

There is currently a mismatch on Unibet where they odds on Roosters for the win is $1.86 but the Line for the Dolphins of +1.5 is $1.85, essentially they are deeming the game so close that a 1 point difference is enough to swing the bets either way.

Dolphins +1.5 is the better bet here but realistically more value (10 cents more) is going the Dolphins on the nose.

OVER UNDER tempo is floating around 49 and the predicted score comes in at 43, the OVER/UNDER at Unibet is set at 48.5 so we recommend going to UNDER.
