Keith Law's condescending attitude gives sabermetrics a bad name. Law's pompousness obscures his otherwise valid data.
I have a theory about the resistance to advanced baseball metrics, which often challenge conventional wisdom.
For many of us, that conventional baseball wisdom was passed down to us by our fathers. Any challenge to that wisdom can be interpreted, at least subconsciously, as an insult to our father. Hence, the sometimes emotional reaction.
At least that's my theory ...
On the other hand, my father, who died in 1988, likely would have welcomed advanced baseball metrics because he remained interested in learning until the day he died.
