|About the stats|
Over the course of his career, Jack O'Connor made 5,794 plate appearances. O'Connor was worth 9.2 Wins Above Replacement and -10.1 Wins Above Average.
After adjusting for length of schedule, catchers, and relief pitchers, the 9.2 WAR becomes 11.2 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 -10.1 WAA becomes 5.4 adjWAA.
Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA. This gives O'Connor 20.9 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).
Jack O'Connor has a Hall Rating of 20, leaving him nowhere close to induction to the Hall of Stats.
