Campen, who played center for the Packers from 1989 through 1993, joined the coaching staff in 2004 under then-head coach Mike Sherman as the team’s assistant offensive line coach. When McCarthy took over for Sherman in 2006, he kept Campen and offensive line coach Joe Philbin, despite not knowing either of them well.

The decision worked out for McCarthy, who then promoted Philbin to offensive coordinator and Campen to offensive line coach in 2007. Philbin helped the offense to two of its highest-scoring seasons in team history, and Campen developed a host of middle-round draft picks into Pro Bowl-level players.

Since 2010, the Packers have had six offensive linemen selected to the Pro Bowl — making Campen the only line coach over that time to send that many different players to the league’s annual all-star game.

From guards Josh Sitton (fourth round, 2008) and T.J. Lang (fourth round, 2009) to left tackle David Bakhtiari (fourth round, 2013) and center Corey Linsley (fifth round, 2014), the Packers consistently developed mid-round picks into starters.
