|About the stats|
Over the course of his career, Harry Luff made 457 plate appearances and pitched 68 innings. Luff was worth -2.7 Wins Above Replacement (-0.6 as a hitter and -2.2 as a pitcher) and -4.3 Wins Above Average (-1.5 as a hitter and -2.7 as a pitcher).
After adjusting for length of schedule, catchers, and relief pitchers, the -2.7 WAR becomes -2.1 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 -4.3 WAA becomes 0.3 adjWAA.
Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA. This gives Luff -1.6 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).
Harry Luff has a Hall Rating of -1, leaving him nowhere close to induction to the Hall of Stats.
