That length and breadth of McGrattan's experience inside the game, the respect he's earned for conquering his alcohol addiction and the willingness to share his story in order to enlighten others, make him an ideal person for this job.
"In 15 years of pro experience, I've gone through just about everything,' says McGrattan. "And, yeah, I may be retired, but I still consider myself a player.
"I'll always consider myself a player.
"That's how I think.
"I don't want the guys here now to look at me as a person who works for management but as a fellow player. As somebody who's been there, like them. Who knows: the uncertainties, the highs and the lows - all of that.
"One of my biggest attributes as a player was with me it was always team first.
"Always.
"When I was fighting and doing all that stuff, I'd die for my teammates. That's how I was."
Another tough gent, Brantt Myhres, has been hired in a similar role by the L.A. Kings. McGrattan feels their jobs, or a variation on it, should be mandatory for each of the 31 NHL clubs.
"When I was playing and I had I had no one to talk to,'' he says. "No one.
"I wish had someone with experience in this kind of position when I was playing. Being a player who went through off-ice issues, I had to do everything on my own. Even some of the league resources were very limited.
"This role provides a good outlet for players. Questions, concerns about the pro lifestyle, especially for younger guys coming in. Someone for players to vent on. I'm looking forward to it.
"It's going to be a good learning curve for me and the organization. We'll take it day-by-day and see how it goes."
