Carolina vs. Michigan State: +/- and Defensive Charting

Before getting to the first +/- table of the season, some words of caution: single-game +/- figures are so “noisy” (i.e., influenced by randomness) that they’re rendered practically useless. Even with a complete season’s worth of data, the +/- metric (especially in this– its unadjusted– form) suffers from this noisiness. Still, when taken in conjunction with the defensive box score, traditional box score, and old-fashioned “eye test,” the single-game +/- can be a part of the total evaluation process. It also serves as a good summary of Roy Williams’s substitution patterns/rotation.

Some definitions:

Pts-Pts All.: the points scored and points allowed by the team during a given player’s minutes
Off Eff: the points scored per 100 possessions with a given player on the court
Def Eff: the points allowed per 100 possessions with a given player on the court
Net Eff: the scoring margin per 100 possessions with a given player on the court
