Herb Williams was worth +23.4 in blocks alone, more than his entire career total of -5.2 once everything else is counted against him. 1985-86 was the high-water mark, worth +4.8, 42nd that season and 3294th of 24,555 player-seasons on record. On the credit side, blocks (+23.4), rebounds (+9.0) and points (+1.5). On the debit side, free-throw percentage (-9.6), three-pointers (-9.0) and steals (-6.6). The 1071-place difference between his two bases is not noise: it is what he was worth per night set against how many nights he played.
