Theo Epstein greatest move and probably in all of baseball was when he signed David Ortiz to a one year non guaranteed deal when the Twins released him and the rest is history. Theo made mistakes he's like everyone else nobody is perfect but overall he still the best GM that the Red Sox ever had he could draft and recognize talent, he did some good trades like Beckett, Lowell and Schilling, he understood analytics and what it took to win. Hired good people who knew baseball like Terry Francona and Joe Maddon. Overall he the best we've seen on the Red Sox front office nobody will come close to his record in the modern era of baseball
