The Green Bay Packers aren’t blitzing often under new defensive coordinator Mike Pettine, but when they do, it’s been highly effective.

According to Ben Fennell of The Athletic, opposing quarterbacks have a 26.1 passer rating when blitzed by the Packers this season, making Pettine’s group the best in the NFL at affecting the quarterback when blitzing through four games.

The blitzes have been especially effective on third down. Pettine has found unique ways to manufacture pressure, typically by loading the box with potential blitzers to confuse the protection assignments and clear rushing lanes, particularly off the edge from the slot.

Opposing quarterbacks have a passer rating of just 52.4 on third down against the Packers, a direct reflection of Pettine’s ability to cook up pressure.

Rookie quarterback Josh Allen couldn’t handle most of Pettine’s blitzes last Sunday, throwing an interception into the end zone before the half and taking five sacks when Pettine blitzed, per Fennell.

It will be interesting to see how veteran quarterbacks, such as Lions quarterback Matthew Stafford on Sunday, handle the blitzes. Several times last Sunday, Allen missed hot reads and made bad decisions under pressure.

Stafford had a complete understanding of Dom Capers’ scheme and often dismantled the Packers defense in meetings late in his tenure. He knew every pressure look and how to get it blocked pre-snap. Will Pettine be able to confuse him with different coverages and blitzes Sunday?

The Packers don’t have an elite pass-rush, and they lack the game-changing edge rushers needed to win one-on-one in important situations. That’s been fine early in the 2018 season, mostly because Pettine has been so good at scheming up the right blitz looks.
