2009-10: Matt Finn skated for the Toronto Marlboros Midget AAA in the GTHL. He scored 22 goals with 35 assists for the Marlies. One of four Marlboro Midgets selected in the first round of the 2010 OHL Priority Draft, Finn was selected by Guelph Storm with the 12th overall pick.
2010-11: Finn skated in 60 games for the Storm in his first OHL season and played for gold medal-winning Ontario at the 2011 U17 World Hockey Challenge. On a Storm team that allowed more goals than it scored, Finn finished with an even plus/minus and scored 2 goals with 18 assists and 23 penalty minutes. In the first round playoff series with Saginaw he had 3 assists and was plus-3. In five games at the WHC, he scored 1 goal and had 4 penalty minutes.
2011-12: Finn was the leading scorer amongst defensemen for Guelph in his second OHL season. In 61 games he scored 10 goals with 37 assists and was minus-13 with 58 penalty minutes. In a heart-breaking series that saw the Storm win the first two games only to have Plymouth win four straight (including Game 6 in overtime), Finn had 2 assists and was minus-one with 10 penalty minutes. Finn was rated 16th amongst North American skaters in Central Scouting's final rankings prior to the 2012 NHL Draft.
Finn's game relies on his defensive smarts and his penchant for making few mistakes. Defensively, Finn's game is well developed at this time, and that is likely to be his stock in trade when he lands in the NHL. There may be some offensive upside to his game, but he will be primarily known as a heady defensive defenseman.
Finn is playing for the Guelph Storm of the OHL in the 2012-13 season.
