Friction between Packers quarterback Aaron Rodgers and ousted head coach Mike McCarthy escalated throughout the 2018 season in part due to Rodgers's tendency to regularly change McCarthy's play calls at the line of scrimmage, according to reports from Sports Illustrated's Kalyn Kahler and Albert Breer.
According to Kahler, Rodgers has long had the autonomy to change plays on the field as he saw fit. During the Packers' start to this season's 4–7–1 campaign, Rodgers reportedly resorted to that right more than then-coach McCarthy would have liked. The rift between the two added to Green Bay's season full of drama and contributed to McCarthy's firing on Sunday.
