I am not sure how most Fantasy Baseball leagues run, however in my league, pitchers are a dime a dozen. To me, the team the pitcher is going against means more than the pitchers abilities. There are certain starting pitchers that dominate and are in a league of their own, however after that, the most of them are replaceable. Johan Santana is one of the only pitchers that I can think of that are completely trustworthy. Another thing is when you start a pitcher that only gets one start a week and they blow it, you completely blew up your ERA and WHIP on top of losing a whole week from one pitcher.
