Brian Belichick, the New England Patriots' safeties coach for the past five seasons, will not return for the 2025 season. The youngest son of former head coach Bill Belichick has been with the team for nine years, progressing from personnel assistant to safeties coach. His coaching style has been praised, notably by safety Jabrill Peppers, who noted his high standards and unique perspective on the game.

Under new head coach Mike Vrabel, who replaced Jerod Mayo after a disappointing season, the Patriots are in the midst of a coaching transition. Vrabel has brought in Terrell Williams as the defensive coordinator and is exploring options regarding the retention of Belichick and cornerbacks coach Mike Pellegrino. Bill Belichick, meanwhile, is set to start his first season at the University of North Carolina.
