If the Green Bay Packers switch from a 3-4 to a 4-3 style defense under new defensive coordinator Jeff Hafley, the change will have an obvious impact on the defensive front, along with how general manager Brian Gutekunst goes about addressing the interior defensive line and edge rusher positions this offseason.
We still can’t say with certainty that this switch is going to take place. However, there very much seems to be a willingness with Hafley to mold his defensive system to the personnel he has to work with, not to mention that in his four year as head coach at Boston College, the Golden Eagles utilized a 4-3 scheme.
