|About the stats|
Over the course of his career, John Cahill made 963 plate appearances and pitched 50 innings. Cahill was worth -4.8 Wins Above Replacement (-3.4 as a hitter and -1.4 as a pitcher) and -8.2 Wins Above Average (-6.4 as a hitter and -1.7 as a pitcher).
After adjusting for length of schedule, catchers, and relief pitchers, the -4.8 WAR becomes -5.1 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 -8.2 WAA becomes 0.0 adjWAA.
Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA. This gives Cahill -5.1 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).
John Cahill has a Hall Rating of -5, leaving him nowhere close to induction to the Hall of Stats.
