It used to happen in the Manning/Brady days:
History of Accusations
"Spygate" Allegations: Following the initial Spygate investigation in 2007, several former New England employees alleged that the Patriots would frequently scramble or jam the opposing team's coach-to-quarterback headset frequencies during games at Gillette Stadium. One team reportedly asked an NFL official to sit in their coaches' box to witness it happen.
Specific Incidents:
- 2007 Browns Game: A team source for the Cleveland Browns claimed their coaches lost communication with quarterback Charlie Frye eight to ten times during a game in Foxborough.
- 2006 Jaguars Playoff Game: Former Jaguars coach Jack Del Rio stated his team's headsets "mysteriously malfunctioned" for most of the first half of their playoff loss to the Patriots.
- 2015 Steelers Game: During the 2015 season opener, the Pittsburgh Steelers experienced significant headset problems, including picking up the Patriots' radio broadcast in their headsets. The NFL attributed this incident to a stadium power infrastructure issue exacerbated by inclement weather, a statement the Steelers questioned.
- Other Teams: Representatives from several other teams have also reported experiencing similar problems with their coaches' equipment when playing at Gillette Stadium.
