The Jets upped the lead to two when Perreault's 45-foot slapshot from the point found the cross bar and fell just outside the crease where Patrik Laine was waiting to swat home the rebound for his first of the season.
"We have that game right where we want it. (At) 3-1, into the second period, playing well, and doing a lot of good things," said Wheeler. "It takes some confidence in who you are individually, what you do as a team, to realize that a goal here or a goal there, it's not the end of the world.
"(After that) the momentum swing was heavy, and from there we got away from our game, and started to go on our own page a bit. That's the kiss of death."
After the Jets couldn't further increase the lead on their first man advantage of the second period, the Flames turned up the pressure. Mason made a big sliding save on Curtis Lazar on a 2-on-1 with Gaudreau, but shortly after, Brodie would get his second of the night. Just like his first, his point shot made its way through traffic and beat a screened Mason to cut the Jets lead to 3-2.
"Mase makes a huge save for us on that 2-on-1, and at that point, you get the puck back, and you want to get that puck out of the zone for him," said Adam Lowry, who played 17:21 in the loss. "He's just made a huge save, saved us a goal. Rather than getting the puck out of our end, it ends up in the back of our net.
"It's frustrating. You want to play well in front of a new guy, you want to let him get comfortable. We haven't done that in the first two games."
