|About the stats|
Over the course of his career, Nap Lajoie made 10,471 plate appearances. Lajoie was worth 107.2 Wins Above Replacement and 67.4 Wins Above Average.
After adjusting for length of schedule, catchers, and relief pitchers, the 107.2 WAR becomes 111.0 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 67.4 WAA becomes 71.7 adjWAA.
Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA. This gives Lajoie 240.1 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).
Nap Lajoie has a Hall Rating of 226, making him not only a member of the Hall of Stats—but one of the very best players of all time.
