for arguements sake - let's say my rotation is Seaver, Koufax, Pedro, Big Unit. for my 5th starter, I use one guy who had 1.99 ERA, .154 OAV & .90 WHIP & .445 HR/9 over 18 starts, pairing with a guy of similar numbers over 15 starts. Can I treat these two like ONE STARTER over 30 starts and still expect that kind of production?
