2014 - MARS and ChiPS Ratings After R2

Before performing the analysis tonight I thought that team ChiPS Ratings would have been much more affected by the results of Round 2 than team MARS Ratings but, as it turns out, Ratings were similarly affected for both Ratings systems.

For only four teams are ChiPS Rankings more than a single place different from MARS Rankings:

• Collingwood is ranked 6th by ChiPS and 8th by MARS
• Sydney is ranked 10th by ChiPS and 6th by MARS
• Port Adelaide is ranked 7th by ChiPS and 9th by MARS
• St Kilda is ranked 15th by ChiPS and 13th by MARS

Six more teams have ChiPS and MARS Rankings differing by a single spot - Richmond, the Kangaroos, Essendon, West Coast, the Brisbane Lions and the Gold Coast - while the remaining eight teams have identical ChiPS and MARS Rankings. Some of the gaps between teams are more or less assailable in a single round, but the rankings are remarkably consistent.

Lastly, the correlation between ChiPS and MARS Ratings increased a little this week, rising from +0.977 to +0.983. Team Rating Systems, it seems, have much in common.
