Subban is the younger brother of Montreal defenseman P.K. Subban and Boston goaltending prospect Malcolm Subban. While his skill set does not appear to be on the elite level of his brothers and he is smaller than most NHL defensemen there are characteristics of his game that attract attention. An offensively-inclined defenseman with a heavy shot and solid skating abilities, he relishes the physical side of the game and is not afraid to compete with players who are much bigger in stature. As with many young defensemen who like to join the attack Subban is a work in progress when it comes to realizing his defensive responsibilities.
