I loved reading this. To be brief in reply, I welcome the new detailed statistical tools, but I don't bury my head in them. I'm grateful that others do, because as you said, they can enhance our understanding, and I guess that makes me a freeloader to some degree, letting the rest of you study in detail what I am happy to know in the abstract. For example the stats tell us that Pelfrey and Hughes are fly ball pitchers with possibly high FB% (verify) and I wouldn't have known that without being on Twins Daily; and won't an outfield of Buxton & Hicks be nice then? And we are just a year away from that. So with this knowledge, I am optimistic Hughes and Pelfrey were good signings. Kudos to Ryan. But in the end, as a casual fan, BABIP doesn't tell me much more than simple batting average already tells me. There is a degree of chance, luck, funny hops and diving grabs that happen in every game that will skew any statistic in any direction.. Same with SIERA and ERA+ for pitchers. I do take heed to the advanced stats, but at the same time, basic ERA is simple, familiar, and usually tells its piece of the story accurately enough.
