2011-12: Percy made his pro debut — appearing in one regular season game and three playoff contests for the AHL's Toronto Marlies — following an injury-filled third junior season that included two concussions and an October knee injury. He had an assist in his AHL debut on April 15th against Adirondack and played all three games in the first round series with Rochester; finishing plus-one with no points nor penalties. Limited to 34 games during the regular season for Mississauga St. Michael's, he scored 5 goals with 25 assists and was plus-18 with 41 penalty minutes. The Majors reached the playoffs after finishing fifth in the Central Division. Percy was minus-two in the six-game series with Barrie; scoring 1 goal with 1 assist and getting 4 penalty minutes.
Percy possesses all-round capability, and is very calm under pressure situations. He moves the puck efficiently out of the defensive zone and has untapped offensive potential – although he is unlikely to develop into a premiere offensive defender. His focus over the next few seasons will be developing all-round strength (specifically leg strength) to compete for a spot at the pro level.
Percy will play in the OHL for the Mississauga Steelheads in the 2012-13 season.
Projection: Second-pairing, two-way defender.
