2. Multiple defensive fronts
Ever since former Packers’ defensive coordinator Dom Capers was hired in 2009, Green Bay has run the 3-4. It was once a defensive front that many teams stayed away from, but has become more and more popular given the emphasis on the passing game in recent seasons.
New defensive coordinator Mike Pettine is also very familiar with the 3-4 and uses it as his primary base. However, he might run some 4-3 as well in order to give offenses different looks to prepare for. This is an extremely exciting development.
The Packers might have the right personnel to run the 3-4 as well. They are thin at inside linebacker so using Blake Martinez as the only one on the field makes sense. They could move Oren Burks or Josh Jones to one of the outside spots in order to give them flexibility if they want to slide Nick Perry down to one of the defensive end positions.
Their defensive line depth is what really makes the 4-3 doable. They have the obvious three in Kenny Clark, Mike Daniels and Muhammad Wilkerson. However, they have good depth behind them. Dean Lowry and Montravius Adams both have potential to fill in and help provide different looks as well. Keep an eye on this as they move through training camp
