When Mike McCarthy was fired in Green Bay and replaced by Matt LaFleur, the young coach opted to retain McCarthy’s defensive coordinator, Mike Pettine. The Packers then went on to win 13 games each of the next two years, reaching the conference championship game both times. That made it at least a little bit surprising when LaFleur opted to move on from Pettine.
His replacement came in the form of Joe Barry, a legacy coach with a ton of experience. Barry grew up a coach’s son, his father being a longtime offensive line coach in the college ranks.
