Wolf is a big, power forward with some offensive elements to his game. He plays a high energy game with a lot of combativeness and creates havoc with crunching body checks.
Wolf returned to Germany to play for Hamburg in 2015-16 following one season in North America. The Calgary Flames tendered him a qualifying offer, retaining his rights as a restricted free agent. Wolf's size and crash-and-bang demeanor could provide some value to an NHL club in need of toughness but at 26-years-old he is equally likely to spend the rest of his career in Europe.
