|About the stats|
Over the course of his career, Mike Morrison pitched 504 innings and made 306 plate appearances. Morrison was worth -6.0 Wins Above Replacement (-5.9 as a pitcher and -0.1 as a hitter) and -8.6 Wins Above Average (-8.4 as a pitcher and -0.2 as a hitter).
After adjusting for length of schedule, catchers, and relief pitchers, the -6.0 WAR becomes -5.0 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 -8.6 WAA becomes 0.0 adjWAA.
Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA. This gives Morrison -5.0 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).
Mike Morrison has a Hall Rating of -5, leaving him nowhere close to induction to the Hall of Stats.
