Matthew Tkachuk wasn’t happy with the team’s performance even as Flames fans were calling for 10 goals by the end of the game. Calgary’s nine goals were tied for the most in franchise playoff history.

“Not good. Not good at all,” Tkachuk said. “Probably our worst game of the playoffs so far. We got super-lucky…. That’s just not the recipe for success. Maybe we win this one, but we’re not going to win many more if we’re going to play like that.”

Flames coach Daryl Sutter called the Game 1 win a “strange game.”
