Severson can play on both ends of the ice, but recently, his offensive game has started to take off. This past season he led all Kelowna blueliners in scoring. He tries to model his game after fellow Rockets alum and current Nashville Predator star Shea Weber. He displays a calm and poised demeanor with the puck, which helps accentuate his top-notch puck-moving skills. He's equally adept at launching an offensive attack with sharp outlet passing as he is rushing the puck up the ice with his good skating ability. He also has a heavy shot that he is not afraid to unleash. Defensively, Severson puts himself in good position to make the right play. His physical game has gotten better, but his breakout passes are an area to improve upon.
Following a great year with the Rockets, Severson is looking more and more like a dependable top four defenseman. He possesses the requisite skills and all-around game to flourish in all three zones, as well as contribute on special teams. He’ll return to the Rockets for his final season in Kelowna.
