If there is one constant in the way Los Angeles Dodgers general manager Ned Colletti explains the building of a championship roster, it's that you can never have too much pitching. And when it comes to the playoffs, those arms are particularly precious commodities. The starting arms, even more so. Matchups on the mound can swing the course of a series, and there's no such thing as being too flush with riches. Obviously, there's more to a win or loss than who takes the hill first, but the potential advantage marked by a team's respective starters can be huge.
