Query: Stick to the research; stop the similies

Comprehensively researched book that's marred by surprisingly poor writing. Alan Schwartz has done a great job of bringing to light both the evolution of baseball's traditional statistics and the discoveries by "outsiders" who have changed the way we understand the game in the past 25 years. He gives credit where credit is due and isn't afraid to kick the shins of those who deserve it -- from baseball's official statisticians to noted author Thomas Boswell. If he'd just lay off the amateurish similies and metaphors, he would earn a "5" in my book.
