Not arguing about any of your points, just some of the numbers.
Assume your using bb-ref for dWAR, since I don't think Fangraphs does it? 2018 dWAR leaders: Betts 1.7, JBJ 0.8, Moreland 0.5, Beni 0.3, Bogey 0.1. All the rest were zeroes or negatives, with a team season total of 0.2.
Eeegads, the 2025 Red Sox team season total dWAR is also 0.2! Here are our positives: Rafaela 1.3, Bregman 0.8, Narvaez 0.8, Hamilton 0.6, Abreu 0.5, Wong 0.3, Story 0.2, Mayer 0.2, Sabol 0.1.
This whole dWAR stat may be overrated... how in the world is '25 Devers possibly a -0.6? Was he too negative being too defensive about playing the field? If he never steps onto the diamond without wearing a batting helmet, doesn't that literally make him -- some will like this -- a total zero?
