|About the stats|
Over the course of his career, John Cassidy made 2,731 plate appearances and pitched 231 innings. Cassidy was worth -5.1 Wins Above Replacement (-1.2 as a hitter and -4.0 as a pitcher) and -15.4 Wins Above Average (-9.6 as a hitter and -5.7 as a pitcher).
After adjusting for length of schedule, catchers, and relief pitchers, the -5.1 WAR becomes -4.1 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 -15.4 WAA becomes 1.2 adjWAA.
Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA. This gives Cassidy -1.9 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 Cassidy has a Hall Rating of -2, leaving him nowhere close to induction to the Hall of Stats.
