NRL Predictions for Round 18
Team Ratings for Round 18
Please note that I have treated most games as being played on neutral grounds, the exceptions being the Titans, Cowboys and Broncos home games. The NRL has announced that all clubs will be moved to Queensland and the games will be played at the same dates and times. However many of the games have their location still listed as TBA on the NRL website. I may have to issue an update later this week if the supposition of neutral grounds turns out to not be true. The most likely game where this might be the case is the Storm versus Knights game.
The basic method is described on my Department home page.
Here are the team ratings prior to this week’s games, along with the ratings at the start of the season.
Current Rating | Rating at Season Start | Difference | |
---|---|---|---|
Storm | 24.02 | 14.53 | 9.50 |
Panthers | 14.40 | 8.88 | 5.50 |
Eels | 10.11 | 1.68 | 8.40 |
Rabbitohs | 8.45 | 7.73 | 0.70 |
Sea Eagles | 7.54 | -4.77 | 12.30 |
Roosters | 3.00 | 10.25 | -7.20 |
Sharks | -2.66 | -0.76 | -1.90 |
Raiders | -3.51 | 6.98 | -10.50 |
Warriors | -4.04 | -1.84 | -2.20 |
Titans | -4.18 | -7.22 | 3.00 |
Dragons | -4.85 | -4.95 | 0.10 |
