Campen served as Green Bay’s offensive line coach from 2007 through 2018, working under McCarthy for 12 seasons. During that period, the Packers consistently fielded strong and durable offensive lines and won Super Bowl XLV in the 2010 season, defeating Pittsburgh 31–25. In his final year with Green Bay, Campen also held the title of run game coordinator.
Before transitioning into coaching, Campen played center at Tulane and later in the NFL with the New Orleans Saints (1986–88) and the Packers (1989–93). He appeared in 67 NFL games and began his coaching career with Green Bay in 2004 as an assistant offensive line coach and quality control coach, earning a promotion to assistant offensive line coach in 2006 and advancing to the offensive line coach position the following year.
After leaving Green Bay, Campen moved through several NFL stops, including the Cleveland Browns in 2019 as associate head coach and offensive line coach, followed by single-season spells with the Los Angeles Chargers in 2020 and the Houston Texans in 2021. His most recent NFL role came with the Carolina Panthers, where he coached the offensive line during the 2022 and 2023 seasons.
Campen’s hiring is notable given his long-standing relationship with Steelers quarterback Aaron Rodgers, who played with him in Green Bay for more than a decade and publicly praised him in a 2021 Instagram post. Rodgers started all 16 games for Pittsburgh in the 2025 season, throwing for 3,322 yards, 24 touchdowns and seven interceptions while leading the Steelers to a 10–7 record and an AFC North division title; Pittsburgh then fell 30–6 to the Houston Texans in the AFC Wild Card round, and Rodgers is weighing whether to return for the 2026 season, with the Steelers reportedly giving him a one-month deadline to decide.
From a roster standpoint, Campen inherits a young offensive line stocked through the draft, headlined by left tackle Broderick Jones (2023 first-round pick), right tackle Troy Fautanu (2024 first-round pick), center Zach Frazier (2024 second-round pick) and guard Mason McCormick (2024 fourth-round pick). He also joins linebackers coach Scott McCurley as a member of McCarthy’s Steelers staff, continuing a collaboration that helped shape one of the league’s most under pressure–tolerant lines in Green Bay.
