Last week Neil posted schedule-adjusted offensive and defensive ratings in a blog post. I had actually planned to add a page like this for every season a few months ago, but I got sidetracked by other projects.
Anyway, Neil's post served as a reminder for me to get this done, so I have added a team ratings page for each season. The ratings can be accessed from the navigation menu at the top of the page.
Here is a screenshot of the team ratings table for the 2011-12 season:
As you can see, the table displays the unadjusted and adjusted margin of victory, offensive rating, defensive rating, and net rating for each team. (Note: adjusted MOV is the same as SRS.)
Margin of victory only requires team and opponent points for each game, so it can be computed going back to the 1946-47 BAA season. However, offensive rating, defensive rating, and net rating require complete team game logs, so they only go back to the 1985-86 NBA season.
Finally I should note that the offensive and defensive ratings on these pages will not match what you see on the team and season summary pages for two reasons:
- The offensive and defensive ratings on the team ratings pages weigh each game equally. In other words, they are found by computing the team's offensive and defensive rating for each game and then averaging them, whereas the offensive and defensive ratings on the team and season summary pages are computed using cumulative season statistics.
- The offensive and defensive ratings on the team ratings pages do not include team turnovers, but the offensive and defensive ratings on the team and season summary pages do include team turnovers.
