|About the stats|
Over the course of his career, John Franco pitched 1,245 innings and made 37 plate appearances. Franco was worth 23.5 Wins Above Replacement (23.6 as a pitcher and -0.1 as a hitter) and 10.2 Wins Above Average (10.3 as a pitcher and -0.1 as a hitter).
After adjusting for length of schedule, catchers, and relief pitchers, the 23.5 WAR becomes 28.8 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 10.2 WAA becomes 14.8 adjWAA.
Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA. This gives Franco 55.4 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).
John Franco has a Hall Rating of 52, leaving him nowhere close to induction to the Hall of Stats.
