The peak came in 1976-77, -3.2, 189th that season and 17756th of 24,555 player-seasons on record. The value came from turnovers (+1.2) and free-throw percentage (+0.2). It leaked back out through steals (-3.1), points (-2.7) and assists (-2.6). Switching basis moves him 250 places, which is the whole argument about availability in a single figure.
