Re: Chris Heisey
The splits thing has been vastly overblown, based on what amounts to reading tea leaves in small samples. But in aggregate, we basically knew what kind of hitter he is. He's got pretty good power, but he won't hit for a ton of contact and won't work many walks. When you don't make a ton of contact and you're reliant on power (which by nature happens less frequently), you're a recipe for streakiness.
Last year we saw the upside of that streakiness -- HRs in bunches. This years we're seeing the downside. The "real" Heisey is that guy in the middle; one who hits about .260/.315/.435 and plays solid defense. Over the course of a season, you get decent production, but in shorter stretches, you roll the dice.
Games are won on run differential -- scoring more than your opponent. Runs are runs, scored or prevented they all count the same. Worry about scoring more and allowing fewer, not which positions contribute to which side of the equation or how "consistent" you are at your current level of performance.
