Earlier in the day, veteran centre Brad Richardson was claimed off waivers from the Canucks, perhaps increasing the need for additional depth down the middle.
In Carpenter, the Flames add a versatile depth forward, who big plays big minutes on the penalty-kill and is a beast in the dot, winning 52.25% of his faceoffs this year.
It was the order of the day for these Flames, who did the bulk of their heavy lifting with the Tyler Toffoli and Calle Jarnkrok trades - both of which, paying immediate dividends and offering a balance to the team's forward corps not seen in years.
"Ryan was a guy we liked a lot. I think he fits the style we play," Treliving said. "He's a north-south player, excellent penalty-killer, plays hard, has some sandpaper to his game and I think he'll fit in well with us."
Often, the best trade is the one you don't make. Tactically, you have to stay disciplined on this and the July 1 Free Agent Frenzy.
And with 31 other GMs frantically working the phones Monday, the cost - both now and the future - was predictably steep.
Hence, the Flames were happy with what they had.
And why shouldn't they be?
At 38-16-8, the Flames have firmly established themselves in the league's upper-echelon, thanks to a hard-working, sustainable system that's given them a Pacific-leading +66 goal differential.
The Flames are one of the NHL's top possession teams, and are now the best - league-wide - in their share of high-danger scoring opportunities (56.54%). It's a key underlying metric that weighs the quality of your chances, for and against.
With a pair of 30-goal scorers, including top-line pivot Elias Lindholm, a Hart Trophy-chasing Johnny Gaudreau, and Vezina-calibre goaltending from Jacob Markstrom, the Flames are poised to make a run.
"We like our team," Treliving said. "Today wasn't about doing anything because we felt we needed to, but it gives us a little more depth.
"I like the makeup of our team. It's a real business-like approach to the team. They're steady at the wheel. We've still got 20, 21 games to go, so there's lots of regular-season hockey left, and we've got to clinch a playoff spot. I like the chemistry of the group. They believe they're a good team. There's a good feel around it.
"I'm glad we could add to it."
