Re: The catcher's stats stats (broken down)
LaRue has actually been passable offensively throughout his career, and it was his arm that made him valuable. I chalk up his offensive struggles this year primarily to his lack of playing time. He's in a really bad catch-22. He can't come out of his funk until he plays more but he won't play more until he hits better.
I think that given his usage to date, he likely has at least 3-4 years left as a major league catcher and that he'll resurface somewhere as a starter and put up a few years of .750+ OPS. There's no reason he can't be a .250/.325/.425 guy. You just don't see people fall this hard, this fast, for no apparent reason -- particularly after trending upwards for 4 years.
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.
