I made that same argument on this board in 2002. I presented as much evidence as you did as well. Since then, I've studied the matter a lot and realized just how wrong I was. You are correct that defense is not even 50% of the game but it is still very important. Every non-out made by Betancourt represents about 2/3rds of a run on average. That includes the obvious errors and the not-as-obvious 5 hopper that skitters between Betancourt and 2B. Even if Betancourt only makes 1 less out than an average SS every 5 games, that's still about 20 runs and 2 wins over a full season, which is a hell of a lot. That's the difference between an average major leaguer and a perennial minor leaguer. It's the difference between 87 wins and the playoffs and 85 wins and sitting at home. I hear you, but what is the major indicator of 'defense' that we are using? I quoted the term defense, because I would take it mostly to be runs scored against as opposed to fielding metrics. From this reasoning, I would say that good pitching would not only reduce the runs scored against per game, but it would also serve as a type of equalizer by overcoming poor defense. To me, unearned runs would be a good measure of this (yes, I'm old school). To my surprise, the Brewers are actually 11th/15, while arguably the two best teams in the N.L. are 1/2 (Phi, Atl) so the poor defense arguments seem to have merit. At the same time, I would argue that every team makes errors, so things would tend to even out over the course of a season for the most part unless the team is exceedingly brutal at fielding. Even though the unearned runs are high, it seems that this season the Brewers have benefited more than not by crucial errors and/or misplays.
