"I tried being more serious, being a little more intense,'' Lack says of the hard-to-shake goalie stereotype. "I tried to be a little more in my own bubble.
"Don't get me wrong, when I'm practicing or in games I hate to lose. Then I'm that guy who takes things the most personally. That's when I'm serious.
"I think anyone who knows me, who's played with me, with tell you that.
"But when I'm not doing my job, I found it was better to just be a happy, easy-going guy.
"To be me.
"I feel that's when I perform the best, too. If I'm going to be frowning, be uptight, 24 hours a day, I'm going to be tired when the games start."
What other hockey player has ever had a taco named after him.
"The Lacko Taco,'' laughs David Marcoux, Miikka Kiprusoff's former guru here and Lack's goaltending coach in Carolina last season. "He loves his tacos. He's got a taco tattoo on his forearm.
"The big Mexican restaurant in Carolina, Gonza, did a commercial with him. Eddie actually created this Lacko Taco with smoked, slowly cooked meat.
"And they were really, really good.
"So a fun guy. Around the room, all the boys respect him, like him, for who he is. A real team player.
"Very easy going. Not complicated. Low maintenance as a coach. Before a game he's playing, you can talk with him. In between periods, too. He'd bounce ideas, suggestions, off me, too.
"His work ethic is very, very high. You can be the most lovable guy in the world but at some point you've gotta stop pucks. And the nights he did play in Carolina, there were a lot of quality games."
Lack figures he inherited his innate sense of fun from his dad, Wille, a carpenter.
"He's very talkative, like me. A happy person. But he's got that part of him, too, that when it's time for business, it's business.
"I would say I'm similar to him in a lot of ways."
Do those similarities extend to wielding a lathe or a power-drill, too?
"Well, we're actually working on a couple of things this summer together, around the house. I try to do the boring stuff he doesn't want to do. Tightening screws. Painting.
"Nothing too demanding."
The demanding part starts mid-September, dovetailing into the opening of training camp.
Busy getting things organized for his move here, Friday was Lack's first time on the ice in a couple of weeks.
"I was,'' he acknowledges, "a little rusty.
"But the last month or so I've been really eager to get going again.
"Just super excited to get back into the routine. You meet your teammates. You get to know them. You get back into the rhythm of practices and games.
"That's what I love about hockey. The opportunity to go out there to battle with those guys every day."
