ESPN The Magazine consulted Allen Guttmann, Emily C. Jordan Folger Professor of English and American Studies, about his thoughts on what some consider the split personality of New England Patriots football coach Bill Belichick. "The equivalent figure is Andrew Carnegie," Guttmann said in the piece. "He was a fairly ruthless entrepreneur in the steel industry. And there were bloody strikes at the Carnegie mills. He didn't lose a lot of sleep about that. At the same time, the guy was endowing libraries all over the country and setting up foundations. So he was on both sides of the fence."
