Where they come from
Before we get to the numbers, you should know where they come from. Bill James, who is employed by the Sox as an advisor, and his team of sabermatricians analyze stats and predict future results. Are they always correct? Well quote The Bill James Handbook: We are not soothsayers or mystics with crystal balls; were just a bunch of hairy accountants with spreadsheets. Sometimes were right, and sometimes were wrong, and sometimes were sorry we brought up the subject.
