Pettine was sacked in Cleveland in 2015, but consistently his more talented defenses in Buffalo and NY were among the league's best.
In hiring Pettine, 51, head coach Mike McCarthy plucked a coach off the Rex Ryan tree. He spent the 2013 season as the Bills' defensive coordinator, His unit ranked 10th.
The blitz-heavy 3-4 scheme Pettine employs is similar to Capers', which should give the Packers defense a slightly easier time adjusting to his system. Prior to that, however, Pettine was a successful defensive coordinator.
It was reported earlier in the week that Philbin was interviewing with his former team and NFL Network's Ian Rapoport reported Wednesday that Philbin will be the new offensive coordinator.
Pettine was chosen to replace longtime Packers coordinator Dom Capers, a Cambridge, Ohio native, and graduate of the University of Mount Union. They haven't finished in the top 10 since their Super Bowl-winning year in 2010.
Coach Mike McCarthy also interviewed three in-house candidates for the job: linebackers coach Winston Moss, cornerbacks coach Joe Whitt and safeties coach Darren Perry.
