|About the stats|
Over the course of his career, Pop Williams pitched 386 innings and made 199 plate appearances. Williams was worth 1.5 Wins Above Replacement (0.8 as a pitcher and 0.8 as a hitter) and -1.6 Wins Above Average (-2.2 as a pitcher and 0.7 as a hitter).
After adjusting for length of schedule, catchers, and relief pitchers, the 1.5 WAR becomes 1.6 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 -1.6 WAA becomes 0.0 adjWAA.
Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA. This gives Williams 1.6 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).
Pop Williams has a Hall Rating of 2, leaving him nowhere close to induction to the Hall of Stats.
