I'm late to the discussion here, so I'm going to offer a few points. I'm with TT in believing that saying "pitching and defense" is being too general. Furthermore, I think the further away from the majors you get down the spectrum, the more defense becomes critical. For example the difference in a good fielding high school player, a great fielding high school player, and a poor high school player is huge. So, in the high school game, a pitcher can be a huge victim of poor defense. But, in the pro game, most players are more bunched defensively. Yes, there will occasionally be a player like say Brooks Robinson who is head and shoulders above others defensively and then there are the rare players that may be so horrible with the glove that they do cost their teams significant runs, but for the most part, the difference isn't that negligible. I will agree that preventing runs is critical, but I think that rests far more on the pitcher. I'm not going to say the pitcher doesn't need defenders to do their job, but that most defenders who have made it to the major leagues are capable of making the plays they are asked to make. So, because of that, a player who's only reputation is as a defender is of less value to one who provides more offense than the average player at his position. Now, as to the Cubs using Izturis and Cedeno or Theriot up the middle for defense. A team might could live with that combination if they had strong offense at the corners and in the outfield. The Cubs do not have enough power at those positions to warrant an all-defense, no stick middle infield. We have the needed production at third and first, but if the Cubs go with Izturis-Cedeno/Theriot up the middle, then Murton nor Jones provide enough to help the Cubs be more than a middle division team.
