Just compare JBJ's fWAR as a 165 hitter (2021) to his fWAR as a 225 hitter (2019). It's a 26 run difference on offense (fewer PA's in 2021). The difference in his OBP was 80 points, so that would factor in too.
notin seens fascinated by the fact that the difference between a 165 hitter and a 225 hitter is only one hit a week.
But as a metric-savvy fellow he also knows that the difference is about 2 wins over the season.
His numbers are not that far off of Barnes, who has a career WHIP of 1.33.
It was saying he can't get anybody out that was harsh, not the 2 years part.
