|About the stats|
Over the course of his career, Kirk Gibson made 6,656 plate appearances. Gibson was worth 38.6 Wins Above Replacement and 16.8 Wins Above Average.
After adjusting for length of schedule, catchers, and relief pitchers, the 38.6 WAR becomes 39.5 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 16.8 WAA becomes 19.7 adjWAA.
Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA. This gives Gibson 75.0 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).
Kirk Gibson has a Hall Rating of 70, leaving him short of induction to the Hall of Stats.
