Super 15 Predictions, Round 2
Team Ratings for Week 2
Here are the team ratings prior to Week 2, along with the ratings at the start of the season. Interestingly for 3 teams the ratings have not changed. That is because the Rebels had a bye, and for the Stormers versus Hurricanes, I got the margin correct (rounded to 2 decimal places). My predicted margin was also very close for the Brumbies versus Force game.
| Current Rating | Rating at Season Start | |
|---|---|---|
| Crusaders | 10.29 | 10.46 |
| Stormers | 6.59 | 6.59 |
| Reds | 5.71 | 5.03 |
| Waratahs | 4.30 | 4.98 |
| Bulls | 3.94 | 4.16 |
| Blues | 3.04 | 2.87 |
| Sharks | 1.10 | 0.87 |
| Hurricanes | -1.90 | -1.90 |
| Cheetahs | -2.01 | -1.46 |
| Chiefs | -2.21 | -1.17 |
| Highlanders | -4.65 | -5.69 |
| Force | -4.89 | -4.95 |
| Brumbies | -6.72 | -6.66 |
| Lions | -10.27 | -10.82 |
| Rebels | -15.64 | -15.64 |

I don’t understand how you can have the defending champions rated so lowly. I fail to see the logic of that.

Pretty simple. The Reds have underperformed for years. They started 2011 with a very low rating and had some poor results throughout the year despite eventually winning.

Well, I confess that I don’t really understand how your rating system works. It is effectively a foreign language to me given I know as little about it as a foreign language. I am just trying to get some more understanding of it.
