Whistle-blower: New York Jets
Offender: New England Patriots
Offense: The Jets accused the Patriots of videotaping coaches' signals during their Sept. 9, 2007, game in East Rutherford, N.J.
Fallout: Pats coach Bill Belichick was fined $500,000 and the team was docked $250,000 and a first-round draft pick. Spygate also introduced the world to Matt Walsh (inset), a former Patriots employee who claimed to have been illegally taping coaches' signals since 2000.
