|About the stats|
Over the course of his career, Bill Butler pitched 591 innings and made 133 plate appearances. Butler was worth 1.9 Wins Above Replacement (2.9 as a pitcher and -1.0 as a hitter) and -3.4 Wins Above Average (-2.3 as a pitcher and -1.0 as a hitter).
After adjusting for length of schedule, catchers, and relief pitchers, the 1.9 WAR becomes 2.0 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 -3.4 WAA becomes 0.2 adjWAA.
Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA. This gives Butler 2.4 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).
Bill Butler has a Hall Rating of 2, leaving him nowhere close to induction to the Hall of Stats.
