|About the stats|
Over the course of his career, Ty Cobb made 13,103 plate appearances and pitched 5 innings. Cobb was worth 151.7 Wins Above Replacement (151.4 as a hitter and 0.1 as a pitcher) and 102.1 Wins Above Average (101.9 as a hitter and 0.0 as a pitcher).
After adjusting for length of schedule, catchers, and relief pitchers, the 151.7 WAR becomes 156.0 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 102.1 WAA becomes 102.6 adjWAA.
Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA. This gives Cobb 340.7 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).
Ty Cobb has a Hall Rating of 319, making him not only a member of the Hall of Stats—but one of the very best players of all time.
