Didn't Dozier himself acknowledge that his production differences are partly a result of his position in the batting order? "I like the leadoff approach" and "let's just say the game isn't played on paper" are him strongly implying that hitting elsewhere in the lineup hurts his approach. Or, to phrase it another way, that hitting leadoff improves his approach. Whether we frame it positively that one spot improves his play, or negatively that other spots hurt his play, the effect is the same. I doubt that is lost on Molitor. I don't know that it makes him unprofessional, but like any human, the mental part of the game is a factor. And Dozier is saying that is the case for him and his production. He's letting his own personal preferences override analytics and he doesn't appear ashamed to admit it.
