Re: Carlos Silva
He's very similar to Elizardo except he's had a great defense behind him. He would struggle immensely as a Red given the number of balls in play he allows.
Games are won on run differential -- scoring more than your opponent. Runs are runs, scored or prevented they all count the same. Worry about scoring more and allowing fewer, not which positions contribute to which side of the equation or how "consistent" you are at your current level of performance.
