2010-11: Despite being a 2nd round pick in 2010 NHL Draft, Nemeth wasn’t expected to garner a ton of work in the Elitserien and was projected to perhaps spend some time back in the J20 Super Elit league. However, Nemeth was largely impressive from the get-go and garnered top-four minutes on the Elitserien club AIK. He also represented Sweden at the World Junior Championships stage. Nemeth has progressed very well as a defensive blueliner and will seek an expanded role on AIK next season.
2011-12: Signed to a three-year, entry-level contract by Dallas in April 2011, Nemeth returned to Sweden to skate for AIK in the Elitserien and also played for Sweden at the 2012 U20 World Junior Championship. He skated in 46 games for AIK, which finished seventh in the 12-team league. He was minus-three, averaging over 17 minutes of ice time per game, and had 3 assists and a team-high 55 penalty minutes. AIK reached the Elitserien playoff semifinals and Nemeth was an even plus-minus with 1 assist and 8 penalty minutes in 11 playoff games. Nemeth led all defensemen for gold medal-winning Sweden at the WJC with 5 assists and was plus-seven in six games.
Big defensive blueliner that has very good acceleration. Has a strong first step and a wide skating stride – only average top speed. Can make a fine outlet pass but is not much of an offensive threat. He does like to come charging down the slot to try to pick up loose change if the situation calls for it. Can be a little clumsy with the puck in his own end at times which leads to problems. Could stand to improve his awareness. Perhaps he’s focusing more on positioning than hitting now that he’s at a higher level, but he could stand to make better use of his tremendous frame when he becomes more comfortable with his surroundings.
Potential: 2nd pairing defensive defenseman, like Nicklas Grossman.
Will turn pro in North America in 2012-13.
