"It kind of [ticked] me off, to be honest," Lauko said of the social media doubters.
That added motivation showed, as the Czech native scored his second goal of the preseason while helping to contribute to a strong performance by Boston's fourth line, which also featured Nick Foligno and Tomas Nosek, in a 5-3 setback to the Devils at TD Garden.
"I thought that fourth line, the Nosek line, was our best line, all game," said coach Jim Montgomery. "[Lauko] was good. He's doing what we've asked. He's bringing speed, he's keeping pucks in the offensive zone or taking pucks into hard areas. That's why he's been here this long."
Before Saturday's contest, Montgomery was asked about Lauko's camp and why the 2018 third-round pick had managed to stick with the big club through the entire exhibition schedule. Boston's new bench boss cited the 6-foot, 196-pound winger's unique blend of speed and provocation.
"I think the development team here did a really good job of letting him know how he needs to play," said Montgomery. "He's done the things that are necessary, that I think builds momentum on the third or fourth line especially with his speed, attacking the net, he's physical. He's lippy out there. He's a little bit of an agitator. He gets under people's skin."
In addition to embracing the core strengths of his game, agitating included, Lauko also believes an enhanced focus on conditioning over the offseason has made a difference during his fourth Boston training camp.
"Last season, I had a big expectation of myself that I'll end up with [Boston] to start the season, and it didn't work out. I wasn't good enough," said Lauko. "End of last season was pretty bad. This summer, I was training my battles and hopefully it's going to pay off. I feel pretty good on the ice. I feel comfortable on the puck.
"I think my conditioning is a pretty high tier right now. I feel good today. I feel best in the third period. When I feel like the other guys are getting tired, I feel best. I think that's going to be my staple this season, my conditioning and my ability to skate all game."
