|About the stats|
Over the course of his career, Jeff Robinson pitched 901 innings and made 180 plate appearances. Robinson was worth 2.9 Wins Above Replacement (3.1 as a pitcher and -0.2 as a hitter) and -4.8 Wins Above Average (-4.6 as a pitcher and -0.2 as a hitter).
After adjusting for length of schedule, catchers, and relief pitchers, the 2.9 WAR becomes 3.5 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 -4.8 WAA becomes 2.7 adjWAA.
Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA. This gives Robinson 8.4 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).
Jeff Robinson has a Hall Rating of 8, leaving him nowhere close to induction to the Hall of Stats.
