There was a reunion of sorts at the MIT Sloan Sports Analytics Conference, held over the weekend at the Boston Convention and Exhibition Center. Friday, Michael Lewis, whose best-selling book “Moneyball’’ became a feature film starring Brad Pitt as Oakland A’s GM Billy Beane, sat down with a couple of folks whose pioneering work led Lewis to write the book. Joining Lewis were stats guru Bill James, who advises the Red Sox, and Paul DePodesta, a former assistant GM with the A’s who was the inspiration for the “Moneyball’’ character played by Jonah Hill. James touched on comments made earlier in the week by former Yankees reliever Goose Gossage, who lamented that baseball “is becoming a freaking joke because of the nerds who are running it.’’ The Hall of Famer told ESPN: “I’ll tell you what has happened, these guys played rotisserie baseball at Harvard or wherever the [expletive] they went, and they thought they figured the [expletive] game out.’’ Gossage added, “They don’t know [expletive].’’ James seemed unbothered by the critique. “That’s what’s changed since 2002,’’ said James. “You used to have to pay attention to those guys [like Gossage]. Now you can just ignore them.’’ MIT Sloan Sports Analytics Conference is the world’s largest conference dedicated to sports analytics and business.
