Hjalmarsson is a forward who plays a well-rounded game. Owns both scoring and playmaking ability, and is a hard worker. Although not terribly big, Hjalmarsson is typically strong along the boards and hard to knock off the puck. Has the ability to play any forward position. - Erik K. Piri, EP (2014)
