According to numerous published reports, new Green Bay Packers defensive coordinator Jeff Hafley will make the 4-3 defense the team’s new base. Actually, since most NFL teams use nickel defenses as their base these days, Hafley will likely install a version of the 4-2-5 defense.
“I think this league’s a 4-2-5 league,” Packers GM Brian Gutekunst said shortly after Hafley was hired. “And I think, I’m certain, as Jeff comes in, and we’re very excited about that, the conversations about kind of how we’re going to want to play. Obviously through the interview process we had some of those, so, and that will be a work in progress.
