The Brewers are 10 games up. Someone said without Marcum we'd not be headed for the playoffs. I replaced Marcum's innings with a 5.25 ERA, and that's 40 more runs allowed. I'm not going to try to figure out who replaces who, what, where, why, when and how. There's no way you can measure the Brewers expected W/L based on that, seeing as we're already pretty far ahead of the pythagorean. I'm simply replacing Marcum's innings with 170 replacement innings, regardless if it's 130 from Dave Bush and 40 from a replacement level reliever, doesn't matter. ALL ELSE being equal, if you replace Marcum with crap, the Brewers would still be 6 games up. Of course the problem would be that it would be impossible to say "All else remaing equal" because not having Marcum would have other unknown ramifications on the team (Bullpen usage, salary used elsewhere, etc). I feel comfortable that without Marcum that we would still be in the race; I just have no idea how close the race would be. The offseason could have progressed so much differently it really doesn't pay to speculate where the Brewers would be if they had never completed that trade. In hindsight if they could have found a different starter similar to Marcum that didn't require giving up Lawrie that would have been the best of both worlds; not sure that was possible though. Plugging in Lawrie at 3rd instead of McGehee would be amazing. This is precisely why I have to make the argument "all else being equal". It's impossible to measure the effect of not having Marcum *except* to give a number to the runs allowed in the innings he pitched that others would replace. Would it have a trickle down effect on the bullpen? Maybe, maybe not. Would it have affected getting Greinke? Maybe, maybe not. The only thing that we can for sure measure is the amount of runs X pitcher(s) would surrender in Marcum's innings, and how many wins (pythagorean) we'd have less because of it. I'm not at all discounting the other factors, but trying to measure them is an exercise in futility. Even so, I strongly disagree with the notion that without Marcum, this team is not playoff bound. Marcum's been very good, but he's not a 10 game difference maker by himself.
