I'm sorry but that article is just terrible. If you ever need a textbook example of cherry picking, bookmark that sucker. It's a classic case of forming an agenda first (laud EJ; disparage Marrone), and then attempt to manipulate and contort data until you can fool someone into believing said agenda has merit. By the end of that atrocity I fully expected the author to attempt to statistically blame Marrone for the Clinton prison escape.
That piece is the product of a man with no statistical background, a rudimentary grasp of algebra, and way, way, way too much offseason Kool-Aid. It's also what happens when you delve too deep into the numbers and don't watch the actual games (he does have a future in politics however)
