Van Natta, who co-wrote the story with Seth Wickersham, says they have received more than a dozen calls from various league sources since the story was released.
He did say a couple of the leads involved other teams, although the Patriots remain the main focus.
“We heard from people we didn’t even interview who were confirming the storylines in our piece,” Van Natta said. “It confirmed the anger and paranoia around the league about the Patriots.”
Prior to coming to ESPN, Van Natta covered the White House, Pentagon, the CIA, and spent three years interviewing intelligence officers in Europe for the New York Times. He jokes that all of that experience proved to be “a good training ground” for doing investigative stories on the NFL.
