Brodeur said he knew he would “always be a Devil,” but he had heard that some of the team’s fans were upset that he ended his career with the Blues.

“I have zero regrets,” he said of his time with St. Louis. “I thought it was unbelievable. Just the way they embraced me over there, and for me to understand what another team was like. I was with one team so long, I had no clue what playing for a Western Conference team was like, kind of dealing with all that stuff. Now I get it.”

In May 2015, Blues General Manager Doug Armstrong offered Brodeur a three-year contract as an assistant general manager, but he had to move to St. Louis. Brodeur has four children, ages 16 to 23, with his first wife, Melanie, and an 8-year-old son, Max, with his second wife, Genevieve. It would be the first time since he entered the N.H.L. that New Jersey would not be his home base.

But Brodeur enjoyed the job and made the move.

“I was like a jack-of-all-trades,” he said. “I was with the N.H.L. team, with the amateur staff, with the American Hockey League guys. And hockey at that level is played on the weekends. So I saw my little 8-year-old play hockey only twice last year. That kind of hit me when my wife brought it up to me. I was like, seriously? I was like, it’s time to have something a little more laid back.”

When Brodeur’s contract with the Blues expired after last season, Armstrong said that Brodeur could stay on but that the team would be asking more from him.

“He integrated very well into the whole operation,” Armstrong said. “For him, it was just the time that was needed to commit to the job, because you know he’s 100 percent invested in what he does.”

Brodeur was also a co-general manager of the Canadian team at world championships in May, after helping put together Canada’s Olympic men’s hockey team for the 2018 Winter Games.
