|About the stats|
Over the course of his career, Mike Schmidt made 10,062 plate appearances. Schmidt was worth 106.9 Wins Above Replacement and 73.6 Wins Above Average.
After adjusting for length of schedule, catchers, and relief pitchers, the 106.9 WAR becomes 108.9 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 73.6 WAA becomes 74.6 adjWAA.
Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA. This gives Schmidt 243.2 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).
Mike Schmidt has a Hall Rating of 229, making him not only a member of the Hall of Stats—but one of the very best players of all time.
