Well, for a long time Anderson was using a different form of MoneyBall, an efficient way to get production from not-very-talented or flawed players: avoid the walk at all costs. The problem is that he's no longer convincing his pitchers to avoid walks and they're still not striking people out. Back in the day, Anderson got solid seasons from some pretty terrible pitchers. In the past four years, nearly every pitcher on the staff has underperformed. Outside of Deduno, there isn't a single success story in the rotation. That makes it really hard to defend him, even for those of us who, while not Anderson "fans", didn't think he was awful.
