|About the stats|
Over the course of his career, Jerome Williams pitched 1,029 innings and made 197 plate appearances. Williams was worth 3.4 Wins Above Replacement (4.3 as a pitcher and -0.8 as a hitter) and -5.6 Wins Above Average (-4.8 as a pitcher and -0.8 as a hitter).
After adjusting for length of schedule, catchers, and relief pitchers, the 3.4 WAR becomes 3.1 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 -5.6 WAA becomes 3.7 adjWAA.
Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA. This gives Williams 9.8 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).
Jerome Williams has a Hall Rating of 9, leaving him nowhere close to induction to the Hall of Stats.
