Right now the Cubs are a worse pitching team than they were in 2008 and a worse hitting team than they were in 2008. The point remains they must improve just to get back to last year's level. This is correct. But getting Peavy doesn't address the bullpen or the offense. It does make both weaker, with DeRo and Marshall both being involved. Unless everyone plans on all five of Z, Lilly, Peavy, Demp and Harden starting 32 games and pitching into the 7th or 8th every game, and Marmol, Shark and Gaudin being the only relievers used. do you not realize the upgrade of marquis to peavy is worth much more than the downgrade from kevin hart to atkins? yes, the bullpen gets worse if you trade marshall or whatever. but the rotation gets much, much better. and you can't just assume the rotation boost is equal to the bullpen loss because that's insane. You don't get it, yes the upgrade to Peavy over Marquis is big. But is it bigger then having Cedeno playing 3rd, having a outfield of Hoffpauir, Johnson and Fukudome for a month or longer? Or having Kevin Hart or Mitch Atkins starting when Harden is out instead of Marshall. Having a reliever like Guzman who has the upside to make a difference in the pen. Or having any prospects left to make a deal midseason if any players regress or we have a injury? Peavy over Marquis would be great. But unless you have very good health, making that deal will hurt you overall.
