|About the stats|
Over the course of his career, Ice Box Chamberlain pitched 2,521 innings and made 1,146 plate appearances. Chamberlain was worth 30.8 Wins Above Replacement (30.4 as a pitcher and 0.3 as a hitter) and 14.7 Wins Above Average (14.4 as a pitcher and 0.2 as a hitter).
After adjusting for length of schedule, catchers, and relief pitchers, the 30.8 WAR becomes 26.2 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 14.7 WAA becomes 14.5 adjWAA.
Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA. This gives Chamberlain 52.3 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).
Ice Box Chamberlain has a Hall Rating of 49, leaving him nowhere close to induction to the Hall of Stats.
