Defensive coordinator Joe Barry was hired by the Green Bay Packers under the premise that he would implement a similar system to what Brandon Staley installed with the Los Angeles Rams in 2020. And that's what he started to do last season. Two-high safety looks were predominant, using lighter boxes in comparison to predecessor Mike Pettine.
Now, as the system matures and evolves, a decisive part of the process is to enable Barry personnel-wise to adjust the defense to what he wants to run. If the idea is to use lighter boxes and load up the coverage on the back end, it's imperative to have a great defensive line in place to protect the linebackers.
