|About the stats|
Over the course of his career, Lou Gehrig made 9,665 plate appearances. Gehrig was worth 113.9 Wins Above Replacement and 79.1 Wins Above Average.
After adjusting for length of schedule, catchers, and relief pitchers, the 113.9 WAR becomes 116.5 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 79.1 WAA becomes 79.4 adjWAA.
Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA. This gives Gehrig 259.4 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).
Lou Gehrig has a Hall Rating of 244, making him not only a member of the Hall of Stats—but one of the very best players of all time.
