|About the stats|
Over the course of his career, Jonathan Papelbon pitched 725 innings. Papelbon was worth 23.2 Wins Above Replacement and 13.0 Wins Above Average.
After adjusting for length of schedule, catchers, and relief pitchers, the 23.2 WAR becomes 28.0 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 13.0 WAA becomes 16.5 adjWAA.
Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA. This gives Papelbon 57.7 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).
Jonathan Papelbon has a Hall Rating of 54, leaving him nowhere close to induction to the Hall of Stats.
