Shared History and Experience
Pettine and Parker have a professional history together with the Green Bay Packers. According to SI.com, Parker served as a defensive quality control coach under Pettine, who was the defensive coordinator, during the 2019 and 2020 seasons. Pettine also held the defensive coordinator position in 2018.
Schottenheimer noted that Pettine’s familiarity with the team's defensive scheme and specific players was a factor in the decision. "He has the awareness of some of our players — Kenny Clark, Rashawn Gary — he was a coordinator when C.P. was there, so I think it's just a great fit," Schottenheimer said.
Pettine, 60, brings extensive experience to the role. His career includes serving as the head coach of the Cleveland Browns and as a defensive coordinator for the New York Jets, Buffalo Bills, and Green Bay Packers. Most recently, he worked with the Minnesota Vikings from 2022 through 2025 as assistant head coach and outside linebackers coach. He had retired from football prior to this season but has returned for the Cowboys.
