|About the stats|
Over the course of his career, Fred Lynn made 7,923 plate appearances. Lynn was worth 50.4 Wins Above Replacement and 24.2 Wins Above Average.
After adjusting for length of schedule, catchers, and relief pitchers, the 50.4 WAR becomes 50.5 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 24.2 WAA becomes 28.0 adjWAA.
Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA. This gives Lynn 100.9 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 Lynn has a Hall Rating of 95, making him close to the Hall of Stats borderline—but still on the outside.
