ON SEPT. 9, 2007, in the first game of the season, [Matt] Estrella aimed a video camera at the New York Jets' sideline, unaware he was the target of a sting operation. Mangini was entering his second year as the Jets' coach. Belichick had practically invented Mangini: In January 1995, he saw potential in a 24-year-old Browns PR intern and moved the fellow Wesleyan alum into football operations. Belichick hired Mangini to be his assistant when he coached under head coach Bill Parcells for the Jets in the late '90s, and soon became a father figure of sorts to Mangini, whose father had died when he was young. Then, in 2000, Belichick brought Mangini to New England as defensive backs coach, promoting him to defensive coordinator in 2005.
In 2006, Jets GM Mike Tannenbaum, one of Mangini's best friends and another Belichick charge, wanted to hire the 34-year-old Mangini as head coach. Mangini took the job over the objections of Belichick, who hated the Jets so much that he barely mentioned his tenure there in his official Patriots bio. Belichick revoked Mangini's key card access and didn't allow him to pack up his office. The tension was raised later that year, when the Patriots accused the Jets of tampering and the Jets countered with an accusation that the Patriots had circumvented the salary cap. Mangini, who is currently the defensive coordinator for the San Francisco 49ers and who declined to comment for this story, knew the Patriots inside and out and would tweak his former boss by using his tricks against him, like having a quarterback punt on third-and-long at midfield, one of Belichick's favorite moves.
Then there was the videotaping. Mangini knew the Patriots did it, so he would have three Jets coaches signal in plays: One coach's signal would alert the players to which coach was actually signaling in the play. Still, Mangini saw it as a sign of disrespect that Belichick taped their signals -- "He's pissing in my face," he told a confidant -- and wanted it to end. Before the 2007 opener, sources say, he warned various Patriots staffers, "We know you do this. Don't do it in our house." Tannenbaum, who declined comment, told team security to remove any unauthorized cameramen on the field.
During the first half, Jets security monitored Estrella, who held a camera and wore a polo shirt with a taped-over Patriots logo under a red media vest that said: NFL PHOTOGRAPHER 138. With the backing of Jets owner Woody Johnson and Tannenbaum, Jets security alerted NFL security, a step Mangini acknowledged publicly later that he never wanted. Shortly before halftime, security encircled and then confronted Estrella. He said he was with "Kraft Productions." They took him into a small room off the stadium's tunnel, confiscated his camera and tape, and made him wait. He was sweating. Someone gave Estrella water, and he was shaking so severely that he spilled it. "He was s---ting a brick," a source says.
On Monday morning, Estrella's camera and the spy tape were at NFL headquarters on Park Avenue.
