One of the biggest changes you're going to notice about new defensive coordinator Jonathan Gannon's scheme is his Penny package, which is essentially a 3-4 defense on the line of scrimmage with one true off-ball linebacker, split safeties and another deeper safety in the middle of the field. Green Bay Packers fans are familiar with the 3-4 base defense, which was run by Dom Capers, Mike Pettine and Joe Barry in the past, along with the typical 4-2-4 Nickel defense that is played for the majority of snaps league-wide.
This Penny wrinkle, though, is a little different than what you're used to seeing from most NFL teams. That's why we wrote about what it means for the secondary in an article two weeks ago.
Today, though, I want to focus on the line of scrimmage, particularly with how Gannon is deploying "off-ball" linebacker Edgerrin Cooper.
Generally, when 3-4 defenses play Penny, they take their Will linebacker off the field to add a slot defender. The Packers, as a baseline, don't play a slot defender, but a third safety.
The other change-up Green Bay has is that they aren't taking their Will linebacker (Cooper) off the field, at least with the first-team defense. Because Cooper is one of the team's better defenders, Gannon has actually played Cooper on the edge, displacing the edge defender opposite Lukas Van Ness (generally Barryn Sorrell) this preseason.
