The Red  Sox are one of the teams in baseball that uses a strategy called  moneyball as a large part of their team building philosophy. While they  use a good portion of this tactic, they didn't invent it or make it  popular. Bill James is mainly responsible for this philosophy of  baseball and Oakland A's general manager Billy Beane help put it on the  map. The movie "Moneyball" is about Beane and how he implemented this  approach to his own team. 
After being eliminated by the New York  Yankees in the 2001 playoffs, a trio of star players become free agents  and leave the Oakland A's for greener pastures. Johnny Damon signed with  the Red Sox, Jason Giambi went to the Yankees, and Jason Isringhausen  joined the St. Louis Cardinals. Realizing that these moves could  severely hurt his team, Billy Beane (Brad Pitt) asks the team's front  office for more money and is rejected. After meeting Peter Brand (Jonah  Hill), Beane decides to resort to an unorthodox way of building a team  by utilizing what is called moneyball or sabermetrics.
