See: Two posts above you. 1.) I wasn't here before this season so you have no idea what I would have said about those things. 2.) Cedeno outpeformed Neifi Perez in 2006 which is all that matters. 3.) Rusch (healthy) is a decent option for the price we had him at. He totally busted. Our minor leaguers outperformed him last season, which is all that matters. All of the guys you said the rookies outperformed...so really your points are invalid. I am a very philosophical person. I quote people all the time, and now you allow me a chance to bring up one of my favorite message board banter quotes. Friedrich Nietzsche once defined faith as "not wanting to know what is true." The Cubs may believe they found a flaw in Marquis, but I am not going to have blind hope and I am going to look at it objectively. The facts are that he can't strike guys out, and he walks too many and those things are relatively constant throughout a career. He's not changing them anytime soon. As it has been said, Sean Marshall had an ERA a half of a run below Marquis'. Of course Guzman may not outpitch Marquis ERA wise next season but why not look at the difference between Guzman and Marquis. If you expect an ERA around 4.80-5.00 from Marquis as I do, and then say the lowest Guzman would put up is say, um 5.10 (the more he pitches the more he adapts the better he becomes). ERA for a SP is almost always defined on two things ER allowed and innings pitched by the pitcher. Guzman's higher ERA for five innings on average isn't great, but who is pitching the sixth inning? A decent reliever whose ERA is probably at four at the worst in the games that are close. You make those adjustments and the overall ERA in the same amount of IP is going to be about the same. I did't even mention Guzman's relatively higher probability of getting high ERA's - or the fact that Marquis costs twenty-one million dollars. So would I, but it's still not going to happen. Let's not pretend he's good. Again, see Tim's post. ERA matters A LOT. But ERA itself has little to do with ERA.
