Kalyn Kahler from Sports Illustrated investigated the tension hidden in the Green Bay Packers. According to Deadspin, this tension is evident between coach Mike McCarthy and quarterback Aaron Rodgers. There seems to be a power struggle between the two in who can call the better play. While McCarthy is the play caller, Rodgers has the freedom to improvise and change the play. Sources say the two constantly compete on who can call the better play and get credit for it.
