|About the stats|
Over the course of his career, Jeff Montgomery pitched 868 innings and made 2 plate appearances. Montgomery was worth 20.5 Wins Above Replacement (20.5 as a pitcher and 0.0 as a hitter) and 9.3 Wins Above Average (9.3 as a pitcher and 0.0 as a hitter).
After adjusting for length of schedule, catchers, and relief pitchers, the 20.5 WAR becomes 25.3 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 9.3 WAA becomes 13.9 adjWAA.
Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA. This gives Montgomery 50.3 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).
Jeff Montgomery has a Hall Rating of 47, leaving him nowhere close to induction to the Hall of Stats.
