It was co-written by Paul Solotaroff, a contributing editor to Rolling Stone, and Ron Borges, a columnist at the Boston Herald. Borges has had a contentious relationship with Belichick, and is generally loathed by most Patriots fans. It doesn't surprise me he is the local insider on this article as he has no bridges left to burn with the Patriots organization.
