2009-10: Mathieu Brisebois skated for the QMJHL's Lewiston MAINEiacs as a 17-year-old and played for the Sherbrooke Cougars in Quebec junior A hockey. In 31 regular season games he had 7 assists and was -5 with 22 penalty minutes. Lewiston made the playoffs despite finishing last in the Central Division. Brisebois played in three games in the playoff series against Drummondville and was -4 with no points and 4 penalty minutes. In 32 games with Sherbrooke he scored 7 goals with 9 assists and had 32 penalty minutes.
2010-11: Brisebois joined Rouyn-Noranda after Lewiston folded — skating in 47 games in his first season with the Huskies. He scored 3 goals with 15 assists and was -27 with 32 penalty minutes. Rouyn-Nouranda had the league's worst record; winning just 12 games.
2011-12: Brisebois was the second-leading scorer for Rouyn-Noranda in his third QMJHL season. He scored 17 goals and led the Huskies with 39 assists; finishing -17 with 106 penalty minutes in 68 games. Rouyn-Noranda made the playoffs despite finishing last in the West Division and was swept by Shawinigan in a first round series. Brisebois scored 1 goal and was -6 with 12 penalty minutes in four playoff games.
2012-13: Brisebois was the leading scorer amongst Rouyn-Noranda defensemen as an overage 20-year-old and also finished second on the Huskies with 103 penalty minutes. He scored 19 goals with 54 assists and was +15 in 64 games. The Huskies were one of the big turnaround stories in junior hockey — finishing second in the West Division and reaching the QMJHL semifinals. Brisebois scored 3 goals with 12 assists and was -6 with 24 penalty minutes in 14 playoff games. He signed a three-year entry-level contract with the Coyotes in March, 2013.
An offensive defenseman, Brisebois is a shifty skater and has great puckhandling skills. Eager to jump up and join the rush, he has learned how to pick his spots better as he has matured. He has great vision in the offensive zone and moves the puck well, as well as displaying a great shot and the patience to get it on net. Only average sized for a defenseman, he will also need to improve his skating to improve his play in his own zone.
A late 2013 signing for the Coyotes from Rouyn-Noranda of the QMJHL, Brisebois will step into the AHL to battle it out in his first pro season in 2013-14.
