Yes, the Packers current offensive line coach once played for the team. James Campen was a Plan B free agent signing in 1989. Campen only started one game that season, but became the team’s full-time center in 1990, starting all 16 games.
He served in that role for two more seasons before being replaced by another guy on our list in 1993. Other than his current role, Campen’s greatest claim to fame is that he snapped the ball to Brett Favre in the quarterback’s first regular-season game as a Packer.
