While dad spent his winters north at work, Melissa and the couple's young son Cash stayed at the family home in Vegas.
"I'm sure there were times the absence weighed on him,'' admitted Treliving. "When he'd have a little time, he'd go back to see them. Or they'd often fly into Calgary.
"But it's far from … ideal.
"Family comes above all. We in this business are all away from our families enough, do more than our share of travelling, there's enough separation, it's enough of a pull on anybody."
During his Calgary stay, Engelland settled in to the role of a reliable, if limited, third-pair defenceman. He had all the frills of BLT sandwich but in a Rocky Balboa beat-the-odds sort of persona he found a niche on a team that reached the playoffs in two of his three seasons on patrol (How on Earth can you not take a shine to a guy who admits: "I think the moment I sit back and tell myself 'Gee, I've made it' is probably the moment I'll find myself on my way out").
"He fulfilled all the things we were expecting and hoping for,'' said Treliving. "I think people would say, comparing when Deryk first came to town to his last year, that his contribution grew and grew.
"You need people like Deryk Engelland as part of a team. You really do. A real blue-collar guy. A great example to the younger players of how to train, how to conduct yourself.
"He had a strong voice, a strong presence, in our room. Those are important, often overlooked qualities.
"I think he'd tell you he grew as a player, as leader, as a person while he was in Calgary.
"We wish him all the best.
"Vegas got a good man."
