Hakanpaa brings a very gritty and hard-nosed style of play to the blueline and plays a sound defensive game. A bit limited in terms of his offensive game, he has a massive frame and can throw the body with the best of them. While he skates fairly well for a player his size, it is an area that could be improved.
Hakanpaa returned to Finland in 2015-16, enjoying a successful season with Liiga power Karpat Oulu. A restricted free agent whose rights are held by St. Louis, he has another year remaining on his contract with the Finnish club. The Blues are fairly deep in defense prospects so if Hakanpaa is to make another attempt at playing in the NHL it may be with another club. His stature and physical game suggests he can be an effective stay-at-home defender.
