Jesus, that's even worse. If they traded Z for just Perez, without throwing in any money? I think I'd take that. You would trade a pitcher with an era under 4 when starting for a guy who's era has been in the 6's most of his career starting at roughly the same age? One pitches in a hitters park (Wrigley), and the other pitches in a pitchers park (New York). I realize that people want to blow the team up, but blowing the team up and gaining less productive players at the same age is not going to end well. it's not about acquiring oliver perez, it's about freeing a huge chunk of money for the next 3 years that can (hopefully) be spent to get some very productive players.
