|About the stats|
Over the course of his career, Tom Griffin pitched 1,494 innings and made 466 plate appearances. Griffin was worth 5.5 Wins Above Replacement (4.0 as a pitcher and 1.3 as a hitter) and -7.2 Wins Above Average (-8.5 as a pitcher and 1.3 as a hitter).
After adjusting for length of schedule, catchers, and relief pitchers, the 5.5 WAR becomes 5.8 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 -7.2 WAA becomes 3.6 adjWAA.
Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA. This gives Griffin 12.3 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).
Tom Griffin has a Hall Rating of 12, leaving him nowhere close to induction to the Hall of Stats.
