|About the stats|
Over the course of his career, Rube Marshall pitched 242 innings and made 79 plate appearances. Marshall was worth -1.8 Wins Above Replacement (-1.7 as a pitcher and -0.1 as a hitter) and -3.5 Wins Above Average (-3.4 as a pitcher and -0.1 as a hitter).
After adjusting for length of schedule, catchers, and relief pitchers, the -1.8 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 -3.5 WAA becomes 0.0 adjWAA.
Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA. This gives Marshall -2.1 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).
Rube Marshall has a Hall Rating of -2, leaving him nowhere close to induction to the Hall of Stats.
