|About the stats|
Over the course of his career, Brad Fullmer made 3,065 plate appearances. Fullmer was worth 5.9 Wins Above Replacement and -4.3 Wins Above Average.
After adjusting for length of schedule, catchers, and relief pitchers, the 5.9 WAR becomes 5.9 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 -4.3 WAA becomes 1.8 adjWAA.
Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA. This gives Fullmer 9.1 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).
Brad Fullmer has a Hall Rating of 9, leaving him nowhere close to induction to the Hall of Stats.
