Breslow as a person is a whole issue I won’t embrace because I don’t listen to him speak and after-the-fact stories can be edited to make anyone look anyway the writer wants (assuming a moderately talented writer).
But as a CBO, I don’t accuse him of ignoring the offense. He made changes that haven’t worked, but that’s not the same thing. Certainly he paid attention to pitching and defense, and did so successfully.
But - and I would apologize for the redundancy but I’m not actually sorry - he clearly ignored the bullpen , which is the part of the staff giving up runs…
