The Big Four on the management team of the corporation that is the Green Bay Packers are president and CEO Mark Murphy, general manager Ted Thompson, coach Mike McCarthy, and defensive coordinator Dom Capers. Because McCarthy takes direct charge of the offense, Capers has been given broad authority over all defensive matters, thus raising him a full level above the offensive coordinator and all the other coaches and staff.
The foursome, comprising a straight-line chain of command, has been intact for eight full years now, since Capers joined the other three in 2009. At this point, I view them not so much as four different and diverse individuals, but more as one monolithic management unit.
