|About the stats|
Over the course of his career, John Lannan pitched 862 innings and made 284 plate appearances. Lannan was worth 6.1 Wins Above Replacement (6.8 as a pitcher and -0.6 as a hitter) and -0.5 Wins Above Average (0.0 as a pitcher and -0.6 as a hitter).
After adjusting for length of schedule, catchers, and relief pitchers, the 6.1 WAR becomes 6.0 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 -0.5 WAA becomes 3.4 adjWAA.
Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA. This gives Lannan 12.1 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).
John Lannan has a Hall Rating of 11, leaving him nowhere close to induction to the Hall of Stats.
