He was scoreless and minus-two – averaging just under eight minutes of ice time – in Elitserien play. Playing for Boras he scored his first professional goal, a power play goal, and was minus-five in 12 games. Neither Linkoping (10th) nor Boras (13th) reached the playoffs in their respective leagues. Nermark was a consistent scorer for the Linkoping junior team. In 31 regular season games he scored 8 goals with 13 assists and was plus-10 with 14 penalty minutes.

The smooth-skating Swede is a skilled pivot whose greatest strength is his selfless defensive play. Nermark has the ability to score and produce points but he needs to be more selfish with the puck.
Nermark is likely to spend a few more seasons in the Elitserien developing better hockey sense. He projects as a shutdown player and penalty-kill specialist with some scoring upside at the NHL level.
