With Jonathan Gannon hired as the Green Bay Packers' new defensive coordinator, it hasn't taken long for the defensive side of the ball to experience some change. The Packers have seen two coaches, Ryan Downard and Sean Duggan, leave Green Bay to join ex-Packers defensive coordinator Jeff Hafley’s staff in Miami. However, Gannon made sure to fill the vacancy immediately with a good hire in former Buffalo Bills defensive coordinator Bobby Babich. This season, Buffalo’s defense was ranked 15th in takeaways (20th) and had the best passing defense in the league (156.9 yards allowed). More Green Bay Packers News and Rumors:
