Top 14 Predictions for Round 14

Team Ratings for Round 14

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.

Note that because Lyon is to play Montpellier midweek, there will be a change to those two teams ratings. The changes are likely to be small, but given the closeness of the Brive versus Montpellier match could easily affect that prediction. To deal with this unusual situation, I will post an updated forecast after the Lyon versus Montpellier game, prior to the weekend games.

Current Rating Rating at Season Start Difference
Racing-Metro 92 7.50 6.21 1.30
Stade Toulousain 6.47 4.80 1.70
La Rochelle 5.74 2.32 3.40
Lyon Rugby 4.29 5.61 -1.30
Clermont Auvergne 3.74 3.22 0.50
RC Toulonnais 3.52 3.56 -0.00
Bordeaux-Begles 2.63 2.83 -0.20
Montpellier 1.57 2.30 -0.70
Stade Francais Paris 0.56 -3.22 3.80
Castres Olympique -1.96 -0.47 -1.50

Aviron Bayonnais -4.85 -4.13 -0.70
