|About the stats|
Over the course of his career, John Henry made 227 plate appearances and pitched 140 innings. Henry was worth -1.7 Wins Above Replacement (-0.4 as a hitter and -1.3 as a pitcher) and -3.1 Wins Above Average (-1.0 as a hitter and -2.1 as a pitcher).
After adjusting for length of schedule, catchers, and relief pitchers, the -1.7 WAR becomes -1.5 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 -3.1 WAA becomes 0.0 adjWAA.
Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA. This gives Henry -1.5 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).
John Henry has a Hall Rating of -1, leaving him nowhere close to induction to the Hall of Stats.
