Desjardins is known for his work ethic and it has served him well, because getting noticed by an NHL team proved difficult.
Selected in the 15th round by Sault Ste. Marie in the 2002 Ontario Hockey League Priority Selection Draft, Desjardins was a long shot to play major junior hockey, let alone forge an NHL career. Bringing energy, physicality, determination and defensive responsibility to the ice, Desjardins played four seasons with Sault Ste. Marie, never scoring more than 17 goals in an OHL season.
