Good points, both. First step is recognizing the problem, and why it exists. IMO, they need to move away from the Quinn philosophy, and Jerry's too Get big and physical along the DL. Mazi came to this team claiming he liked to hit people. Well, beef him back up and tell him to start hitting people again. And gets hims some partners to play alongside him.
Watching some videos of the Packers I saw over and over, OL getting downfield to take out our 2nd level defenders. No one on the DL was forcing those linemen to stay in and block or keeping them from getting downfield. This is especially problematic when you have small guys playing LB.
