2011-12: Matteau skated for the NDTP U18 squad during the season but in April was ruled ineligible for the 2012 U18 World Junior Championship by the IIHF. In 46 games he scored 15 goals with 17 assists and had a team-leading 166 penalty minutes. The USA captured its fourth straight gold medal at the U18 WJC tournament. Matteau de-committed from playing college hockey and announced he will play for Blainville-Boisbriand in the QMJHL in 2012-13. He was invited to the NHL Draft Combine and ranked 17th amongst North American skaters in Central Scouting’s final rankings prior to the 2012 NHL Draft.
20012-13: Matteau had an eventful 18-year-old season. He began the year with the QMJHL’s Blainville-Boisbriand Armada and went to camp with the USA U20 team in December (Matteau was one of the final cuts ). He joined the New Jersey Devils after the lockout – skating in 17 NHL games before being returned to Blainville-Boisbriand in March. The season with the Armada came to an abrupt end when he was benched and then suspended following Game 2 of the QMJHL semifinals. Matteau scored his first NHL goal and had 2 assists; finishing -1 with 6 penalty minutes for New Jersey. In 35 QMJHL regular season games he scored 18 goals with 10 assists and was +19 with 70 penalty minutes. Blaine-Boisbriand was first in the West division before falling in the playoff semifinals. Matteau scored 3 goals with 6 assists and was +3 with 16 penalty minutes in 11 QMJHL playoff games.
Matteau plays the game with a lot of energy, passion, and intensity. He uses his big, strong frame to play an in-your-face physical style along the boards and the corners. While not blessed with elite level skill, he has decent hands, a heavy shot and knows how to create space for himself by protecting the puck in the offensive zone. Matteau is well schooled defensively and should become a good penalty killer with his good speed and aggressive nature. However, his borderline style has gotten him into penalty trouble.
Despite his young age, Matteau played a safe, competitive game during his first year with the Devils. As long as he learns to control his aggressive style, he could end up as a complementary second line player. Otherwise, a safe projection sees him developing into a mean, physical, two-way forward.
