Sharks 30–18 Dragons in NRL Round 15 at Sharks Stadium, Sydney. Here's how the result stacked up against the model's call, with the win-probability story and where the value landed.

Sharks 30, Dragons 18 at Sharks Stadium. Straightforward enough on paper, except for the 18 minutes either side of half-time that make the final margin look almost tidy. Dragons led 18-6 at the break. Sharks outscored them 24-0 after it. That's not a comeback, that's a complete reversal of who was winning the football match.

The first half belonged to Dragons, and it wasn't close. Braydon Trindall opened the scoring in the 9th minute, but Damien Cook hit back six minutes later, Lyhkan King-Togia crossed in the 25th, and then Jesse Ramien copped a sin bin in the 31st, with Jack De Belin scoring off the back of it a minute later to make it 6-16. Sharks went to the sheds down 12, a man light for parts of it, and looking like the shakier outfit.

Then the second half happened. Nikora scored in the 48th, Trindall bagged his second in the 53rd, Sione Katoa crossed in the 56th to put Sharks in front for the first time since the opening try, and Katoa added another in the 74th to close it out. Four unanswered tries, zero reply from Dragons.

The stat sheet explains some of it but not all of it. Sharks ran for 2,205 metres to 1,588, a gap that's hard to ignore, and broke 35 tackles to Dragons's 26 while offloading 14 times to 7. That's a side that kept getting go-forward and kept the ball alive in contact, which is exactly how you build second-half pressure. Sharks also held 56% of possession and cracked 5 line breaks to 4.

Dragons, for their part, were the tidier side with ball in hand, just 6 errors to Sharks's 10 and an 88% completion rate to 87%. They also controlled the boot, kicking 850 metres to 704. None of that matters much if your defence can't hold up, and Dragons missed 35 tackles to Sharks's 26. When you're leaking that many tackles, all the territory in the world just means the opposition gets more cracks at you deeper in your own half.

The pre-match numbers had Sharks favoured, rated 1509 to 1391, expected to win by 10.7 with a combined total of 44. The final margin was 12, the total was 48. Both close enough to call it a sharp read, even with the scenic route through an 18-6 deficit to get there. Sharks's backline rating of 1071 against Dragons's 812 looks like it found its mark once the game opened up, even if the Dragons forward pack, rated higher coming in at 1149 to 1041, had the better of the opening exchanges.

Dragons will look at that first half and wonder how they didn't hold on, and fairly enough. They did most things right for 40 minutes. They just couldn't do them for 80.
