When the New York Mets officially introduced Steve Cohen as the team's new owner back in November, he made it clear this would be a new era in Mets history: "I can promise you we're going to act like a major-market team," he assured. He said all the other right things. That he would let the baseball people make the baseball decisions. That they would invest more in their analytics department and player development staff. Most of all, Mets fans appreciated that they could almost relate to a man with an estimated net worth $14.5 billion because he, like them, is a diehard: He attended his first Mets game in 1963, when the team still played in the old Polo Grounds.
