Historical RAPM: 1985 – 1996

From my video library of past games, I have been slowly reconstructing NBA Stint Data for several seasons prior to the start of the Play-By-Play era of statistics tracking of NBA games. This is a lengthy effort in trying to give some insight to interactions between players, at least from a stint level. When the project is more complete, data will become more readily available. Until then, here is a snapshot from the 1985 through 1996 NBA seasons. Currently I have logged 1724 of a possible 12628 games, which is a mere 13.65% completion of those seven combined seasons.

In this post, we show the individual “plus-minus” in form of number of offensive possessions playedpoints scored by the offensenumber of defensive possessions playedpoints scored by opponents, Offensive RAPMDefensive RAPM, and Overall RAPM.

Also included in the table are LOW and HIGH, which are the confidence intervals associated with each RAPM estimate.

Included at the bottom are the standings for those seasons: Sampled, Estimated from Samples, and Actual records. This way you can do a cursory check against the team’s performance over the years to the actual performance. Remember that nothing is perfect when it comes to sampling, but trying our best to gather a census of all games!

I will update periodically. Sampled records are found at the bottom of this page. Enjoy!

SAMPLED: Sampled Win-Loss Record of Observed Games
MLE: Maximum Likelihood Estimate of Team Record from Sampled Games
BAYES: Bayes Estimate of Team Record from Sampled Games
TRUTH: Actual Final Record for the 1985-96 NBA Seasons.
