Jacques Demers coached three World Hockey Association teams as that league was fading away in the 1970s, then followed the Quebec Nordiques into the NHL for the 1979-80 season.
He was fired after that season, then would coach three seasons with St. Louis, four with Detroit, three-plus with Montreal and start two seasons with Tampa Bay. He won a Stanley Cup with goalie Patrick Roy in Montreal.
Demers was known for his tough approach to handling players — pointing out their flaws and overall effort with high-volume agitation.
Which caused Glen Sonmor, Minnesota's great NHL storyteller, to say: "Demers has a four-year contract and a two-year act."
Funny … but pretty much a job description for an NHL coach.
Nowhere in North America's four major men's sports can a coach find himself on the way out as suddenly as in the NHL.
Bill Guerin became the Wild's GM in 2019 and now has completed the exacta: He fired Bruce Boudreau with 25 games remaining in the 2019-20 regular season, and he fired Dean Evason on Monday, with 19 games played in this regular season.
And, yes, Guerin did go quickly to the favored cliché for generations of NHL GMs: "You can't trade 23 players."
