"I was definitely off to a good start last year," Leivo said. "A really good start. Even around the time of the injury, I was picking it up and playing even better; some of the best hockey of my career.
"But, hey. That's the game.
"That's the way it goes."
Leivo suffered a fractured knee-cap during a December home game against the Vegas Golden Knights last year, ending a breakout season only 36 games in.
The 27-year-old was hit from behind as he chased down a loose puck at the defensive blueline, losing his balance and crashing knee-first into the side boards, with the weight of the 6-foot-4, 212-lb. Nick Holden riding him in.
Just like that, everything changed.
But on Saturday, more than 10 months after the season-ending incident, the dynamic left-winger officially began the next chapter of his career, signing a one-year, $875,000 deal with the Flames.
With it, he brings the memories of last year - both good and bad - and is pining to build on a gratifying first half.
"I think I even had an assist that game," Leivo said with a laugh. "I don't know what it was, exactly, but I was feeling great. Every game I tried to raise the bar even more. I guess with an increased opportunity, a bigger role, trust from the coaching staff, I was able to attack every game with confidence.
"It's unfortunate I didn't get to play out the rest of the year. But, if I look at what I was able to accomplish, the roll I was on and the steps that I took, I feel great about bringing that all to Calgary now."
