Packers HC Mike McCarthy said Monday that the arrival of new defensive coordinator Dom Capers will bring a change from the old 4-3 to the 3-4 defense. While he was still open to the 4-3 defense, McCarthy wanted to go after the 3-4. Capers is an excellent fit, said McCarthy. “His vision of playing defense and my vision of how we’re going to go forward in Green Bay, I’m going to say I think is why he is an outstanding fit for our organization.”
