In 57 games he scored 29 goals with 28 assists and was plus-six with 111 penalty minutes (trailing only Capitals’ prospect Tom Wilson (141)). After finishing two points behind OHL champion London in the regular season, Plymouth reached the second round of the playoffs – falling to Kitchener in seven games.

2012-13: Heard made his pro debut as a 20-year-old, opening the season with Colorado AHL affiliate Lake Erie and playing 23 games before being returned to juniors in January. He scored 1 goal with 3 assists for the Monsters and was -5 with 72 penalty minutes. After re-joining Plymouth as an over-age player, he scored 17 goals with 19 assists and was +14 with 34 penalty minutes in 32 games. The Whalers finished first in the OHL’s West Division and reached the Western Conference finals. Heard scored 8 goals with 5 assists in 14 playoff games and was +8 with 37 penalty minutes.
As somewhat of an overlooked player his entire life, Heard has been playing with a chip on his shoulder ever since juniors. The offensive talent is there but so far he hasn’t been able to display it in the AHL.
Heard has developed into an energy player who is willing to stand up for teammates. He may not light up the scoreboard frequently but his history means opposing teams should not take him lightly when in their zone.
