C · 5 seasons · 2000-01 – 2004-05
Jason Collier is the extreme version of a specialist. +4.0 of roto value came from turnovers, yet his career total is only -17.1. 2004-05 was the high-water mark, worth -2.6, 298th that season and 15942nd of 24,555 player-seasons on record. On the credit side, turnovers (+4.0) and field-goal percentage (+0.3). On the debit side, steals (-4.7), assists (-3.9) and points (-3.6). Switching basis moves him 470 places, which is the whole argument about availability in a single figure. 2003-04 is the sharpest single case: -2.6 on totals against +1.5 per game, off 20 games.
