Expectations were high when Lazar broke into the NHL with Ottawa as a 19-year-old in 2014, just a year after the Senators selected him with the 17th pick in the draft. He knows now that his ascension to hockey's highest stage came too soon.
Lazar played parts of three seasons with the Senators and was averaging just 8:49 when they traded him to Calgary in March 2017. He played 65 games with the Flames the following season but averaged just 9:51 and tallied 12 points.
After clearing waivers in October of last season, Lazar - still just 23 - admitted that seeing regular ice time in the minors might be the best course to get his career on track. He spent the year playing in all situations for AHL Stockton, wearing an 'A' while tallying 41 points in 57 contests.
It was the sort of role - and production - that had been lacking since his junior career.
"It was huge, and honestly it was probably much needed for myself," Lazar said. "I got rushed into the NHL as a 19-year-old and, yeah, I was able to stay afloat on the fourth line and stuff but I kind of lost that offensive edge.
"… To come out here and feel good about myself and my game, it feels good. I'm looking for it to translate and get some results."
