Simply put, managers are scapegoats. Teams need someone to take the heat that goes with disappointing hordes of fans and that person is the manager. Although it might be easy to criticize players, we really have no right as they regularly do things that are so beyond our abilities that we can't even really understand how they're doing it.
Managers are different, however, as although we might not fully know or understand their reasons as we look in from the outside, we feel we can boldly criticize to our heart's content. Although we might not admit it, there are times in every fan's life when one is convinced they could do a better job managing. Although this is often disregarded as simple fan arrogance, it's surprising how often managers continue to make legitimately stupid moves that are often scrutinized by fans who believe they could do a better job from their own couch.
With that being said, I present to you a relatively humble attempt at arrogance as I try to construct the optimized lineup that San Francisco Giants manager, Bruce Bochy, should be using.
