Everyone seems to like McCatty, but I again go back to wondering how many pitchers we have that made it to the major leagues and/or came to the team and significantly IMPROVED, which would be a sign that McCatty was actually adding value.
Maybe I'm completely off base here, but there are teams like the Cardinals, Mets, and others where pitchers seem to improve upon access to their pitching coach. Maybe Clippard is a huge success story?
