But this isn't about the course of a career, this is about being able to better qualify individual instances. seeking a way to say that this walk shouldn't count towards some imaginary stats like "quality OBP" because that pitcher was so wild that the hitter shouldn't get "credit" for the walk. all base hits are not created equal, all walks are not created equal, and anyone who pretends they are is kidding themselves. Statistics will never be as reliable a predictor as we would like them to be as long as a "Theriot Special"/roller up the middle that anyone with decent range could get to, counts the same as a rope off the wall that is limited to a basehit, because the runner on first was afraid to advance until it dropped.
