Pettine's record is, to put it mildly, mixed at best. Especially when it comes to stopping the run.
From Wikipedia (I know, I know):
"On January 10, 2018, Pettine was hired as defensive coordinator by the
Green Bay Packers by head coach Mike McCarthy.
[8] On December 2, 2018, the Packers fired McCarthy after a 20–17 loss to the
Arizona Cardinals at home, and he was replaced by interim head coach
Joe Philbin. On January 7, 2019, the Packers hired
Matt LaFleur as their new head coach, who announced he would retain Pettine as defensive coordinator through the 2019 season.
During his time with the Packers, Pettine improved the Packers defense from the league's 29th ranked unit in 2018[9] to the 15th ranked unit in 2019[10] and 17th ranked in 2020.[11] However, he was widely criticized for his calls in the playoffs, particularly in the Packers' losses in back-to-back NFC Championship games. In the 2019 NFC Championship Game, Pettine's defense gave up 285 rushing yards to the NFC champion San Francisco 49ers, on their way to a 37–20 loss. In the 2020 NFC Championship Game, the Packers defense picked off quarterback Tom Brady three times, but also gave up a late first-half touchdown when Pettine called for cornerback Kevin King to cover receiver Scotty Miller one-on-one. Pettine's call was widely criticized by many, including his own head coach.
On January 29, 2021, Pettine was let go by the
Green Bay Packers as the defensive coordinator; his contract had expired and the Packers reportedly did not move to extend it.

My only point is that this guy isn't exactly riding to the rescue. He was, at best, a middle of the pack DC, and he hasn't served as one since 2021. And he retired after the 2025 season. So, he'll watch, he'll advise, and perhaps make some difference around the margins. Or, perhaps not.
