|About the stats|
Over the course of his career, Cotton Williams made 226 plate appearances and pitched 181 innings. Williams was worth 0.9 Wins Above Replacement (0.3 as a hitter and 0.5 as a pitcher) and -1.0 Wins Above Average (-0.1 as a hitter and -0.9 as a pitcher).
After adjusting for length of schedule, catchers, and relief pitchers, the 0.9 WAR becomes 1.5 adjWAR. Then, WAA is adjusted by ignoring negative seasons (thus, truly capturing a player’s peak seasons) and making similar adjustments for catchers and relief pitchers. After these adjustments, the -1.0 WAA becomes 1.6 adjWAA.
Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA. This gives Williams 4.4 wWAR. wWAR is then converted to Hall Rating. A Hall Rating of 100 represents the Hall of Stats borderline (similar to OPS+ or wRC+, where 100 represents league average).
Cotton Williams has a Hall Rating of 4, leaving him nowhere close to induction to the Hall of Stats.
