Of course defense important, but it must always remain in it's proper balance with good pitching and (over hitting) OBP. Defense is 3rd in it's importance (relative to the 3) but still important overall. If you have 9 butchers in the field, but good pitchers and the ability to get on base well, you will have a wide range in the scoring of games, but a monster offense that will win some games 12-2 and lose some at 14-13. If you have the 9 stellar defenders and good pitchers, but no OBP, you're looking at losing 3-1, 2-0 on a fairly regular basis. If you have the defense and OBP, but no pitching, with the Cubs frequency of flyball pitchers you're going to lose, more often than not, really big. If you had sinkerballers, you'd probably win more than lose, but statistically close to a wash. On the Cubs, we have "stellar" defense, below average pitching (flyball pitchers at that), and a much-much-much below average ability to get on base. So, while our top notch defense might save us on grounders, we'd need superior leapers (think 1000"+ vertical) to save us significantly in the RSA department. It's not measurable, and importance might be minimal, but psychologically, especially in tough situations, it can make a pitcher more confident in the approach to the batter to know that if the ball is hit on the ground, the defense can and will field it, and get the out. It's not something to build a team around, but the idea is valid. Improving defense was not what this team needs, unless the byproduct of our improvement means that Cedeno or Izturis adds a piece to a trade puzzle in the offseason that nets us the impact offensive player or #1/2 starter that we have to have.
