DBo didn’t work out obviously, I’m a believer that a pitching coach , or hitting for that matter ,can only do so much. This is not knocking our players, but I’m sure the plan was not to go out and get behind hitters and walk folks. Yes there are instances where a particular coach and player gel together and careers are turned around. This could be as simple as instilling belief into said player. Was Mazzone a great pitching coach, or was it 3 HOF that made him. I’m glad DBo is gone, but not sure a pitching savior is out there
