|About the stats|
Over the course of his career, John McMullin made 1,121 plate appearances and pitched 283 innings. McMullin was worth 1.9 Wins Above Replacement (3.3 as a hitter and -1.5 as a pitcher) and -3.8 Wins Above Average (0.2 as a hitter and -3.9 as a pitcher).
After adjusting for length of schedule, catchers, and relief pitchers, the 1.9 WAR becomes 5.1 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 -3.8 WAA becomes 1.0 adjWAA.
Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA. This gives McMullin 6.9 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).
John McMullin has a Hall Rating of 6, leaving him nowhere close to induction to the Hall of Stats.
