"Credit them, they played a good last half of that third period," Tkachuk said. "We weren't sitting back by any means, but we needed to keep pressing. We didn't let off the gas, but we didn't play as much in the offensive zone as we did in the second period."
The Canadiens opened the scoring at 8:01 of the first period, as newcomer Tomas Tatar tallied his eighth of the year. Brendan Gallagher won a puck battle deep in the offensive zone before it kicked out between the hash marks and onto a tee for the goal-scorer. With a pair of defenders blocking the view of the netminder, Tatar's quick fire squeezed under the glove to give the Habs a 1-0 lead.
The Flames took over in the early part of the middle frame, and evened things up with a powerplay marker at 3:43. Tkachuk and Elias Lindholm rotated up top, which opened up a one-time option at the right circle. Seeing this, Mark Giordano delivered the pass and Tkachuk did the rest with a smoker off the far post and in.
The Flames kept coming in waves and moments later, with all kinds of time in the middle, Lindholm ripped one off the post.
At last, on their 17th shot of the period, the Flames took their first lead of the night. TJ Brodie showed great patience, taking it all the way from the top of the circles around behind the net, before feeding Tkachuk with a beautiful net-front tap-in with 4:07 to play.
Overall, the Flames outshot the Habs 19-7 for a two-period lead of 32-17.
"We knew when it was 2-1, it would have been nice to get a little insurance - a little wiggle room," said head coach Bill Peters. "We probably had some good looks, more so in the second than in the third, and we needed to bear down more on some of those opportunities.
"It's a tough one.
"But we'll get right back at it tomorrow."
