New Packers defensive coordinator Mike Pettine is bringing a new philosophy to Green Bay, and is using OTAs to begin the transformation of the defense.
Pettine, who was hired this offseason after Dom Capers was fired, describes the mental aspects of his defensive system, and why it takes time for players to learn it and then execute it.
He also describes the difference between the mind-set he wants his players in, versus the scheme the Packers will try to run this season.
Green Bay resumes OTAs on Monday.
