Matthew J. Walsh, commonly known as Matt Walsh, was a video operations intern and assistant for the New England Patriots from 2000 to 2003. He became central to the NFL's Spygate scandal in 2007 when he voluntarily provided NFL Commissioner Roger Goodell with approximately 14 hours of video footage and related documents documenting the team's practice of illegally filming opposing coaches' signals from the sideline. The materials included secretly recorded video of the St. Louis Rams' offensive walkthrough practice on 2002-01-30 ahead of Super Bowl XXXVI, which Walsh alleged was done at the explicit direction of head coach Bill Belichick. In exchange for his cooperation and testimony, Walsh received full immunity from criminal prosecution and a confidential settlement reportedly worth around $1 million from the NFL and Patriots organization. His disclosures contributed to the league's punishment of the Patriots, including a $250,000 fine for Belichick, loss of a first-round draft pick, and forfeiture of another. Post-scandal, Walsh has maintained an extremely low public profile, with scant verified information on his subsequent professional activities, personal life, or current whereabouts.
