Spygate was an incident during the National Football League's (NFL) 2007 season, when the New England Patriots were disciplined by the league for videotaping New York Jets' defensive coaches' signals from an unauthorized location during a September 9, 2007 game. Videotaping opposing coaches is not illegal in the NFL, per se; there are designated areas allowed by the league to do such taping. Because the Patriots were instead videotaping the Jets' coaches from their own sideline during the game, NFL Commissioner Roger Goodell deemed it to be in violation of league rules, stating that the act represented a calculated and deliberate attempt to avoid long-standing rules designed to encourage fair play and promote honest competition on the playing field. After an investigation, the NFL fined Patriots head coach Bill Belichick $500,000 for his role in the incident, fined the Patriots $250,000, and docked the team their original first-round selection in the 2008 NFL Draft which would have been the 31st pick of the draft.
