the original discussion began because kyle said that gonzalez was an inferior pitcher to garza. which i disputed; kyle used their fangraphs WAR to attempt to justify his assertion. i don't think that's really an accurate view of garza's ability, since that year was far better than any other year that garza had pitched. plus garza's "traditional stats" (ERA/ERA+) were inferior to those of gonzalez' in the previous two seasons, and gonzalez was just reaching arbitration eligibility for the first time - which put him two years behind garza. that's massive. i don't see garza as having had the same value on the trade market as gio gonzalez. and let's be honest about the a's return for gonzalez - they've ended up being pretty fortunate in that deal. cole is basically reaching his ceiling; he's stayed healthy and his secondary deliveries have really come along. derek norris was a three true outcomes player in the minors and hit .210 the year that he was traded - his contact rate has increased drastically in the majors. he's at or above the ceiling that most people expected him at (which was a mickey tettleton-like catcher). they even got as much out of milone as they could really have expected. brad peacock was the only one who hasn't really panned out, but they still used him to get jed lowrie. even if the cubs could have gotten that kind of return for garza, it's unlikely that prospects ranked that highly are going to turn out as well as those that the a's acquired. and your point about selling low on garza, soto and marmol is a valid one, but that's going to happen sometimes to any organization. just as an example, soto was rookie of the year, followed by a bad season, followed by a very good one, followed by a mediocre one. i suppose they could've gotten something reasonable for him after the mediocre 2011 season, but there was always the risk that he'd have another big year like he did in 2008 and 2010, and then the sale would look like a poor one in hindsight.
