Dan O'Sullivan
4 seasons · 1990-91 – 1995-96
Dan O'Sullivan is the extreme version of a specialist. +4.8 of roto value came from turnovers, yet his career total is only -16.5. 1995-96 was the high-water mark, worth -4.1, 364th that season and 20658th of 24,555 player-seasons on record. Career value accumulated in turnovers (+4.8), and drained away in points (-4.4), steals (-4.3) and rebounds (-4.0). The 233-place difference between his two bases is not noise: it is what he was worth per night set against how many nights he played.
