Alan Williams
F-C · 4 seasons · 2015-16 – 2018-19
Alan Williams is the extreme version of a specialist. +3.5 of roto value came from turnovers, yet his career total is only -15.0. The peak came in 2016-17, -1.5, 269th that season and 13424th of 24,555 player-seasons on record. The value came from turnovers (+3.5) and field-goal percentage (+0.6). It leaked back out through points (-3.5), three-pointers (-3.4) and steals (-3.4). He rates 813 places better per game than on totals, and that gap is the durability story in one number.
