This is going to sound like a rationalization, and to a certain extent it is, but I think the variability of pitchers leads to pitching coaches getting a bit more credit than they deserve. I mean think of the pitching coaches that many fans are aware of for their success outside their own team. Off the top of my head I can list off Bosio, Rothschild, Searage, Cooper, Warthen, Maddux, past guys like Duncan and Black. On the other hand I don't think I could name 3 MLB hitting coaches. Yeah, and I may be way off. It could be that Bosio is a Pitching Whisperer that is able to transform guys and I just don't understand everything he's done to make our staff better. I'll give him the benefit of the doubt because there have been a number of guys who have had dormant potential unearthed under his tutelage. There's also Edwin Jaxon, though. But I think it's just something that is hard for any of us to understand fully. So I never get too worked up about coaching changes.
