|About the stats|
Over the course of his career, Fred McGriff made 10,174 plate appearances. McGriff was worth 52.7 Wins Above Replacement and 19.8 Wins Above Average.
After adjusting for length of schedule, catchers, and relief pitchers, the 52.7 WAR becomes 53.7 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 19.8 WAA becomes 26.3 adjWAA.
Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA. This gives McGriff 101.0 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).
Fred McGriff has a Hall Rating of 95, making him close to the Hall of Stats borderline—but still on the outside.
