Andersson's goal came during a stretch of 23:41 between Columbus shots, spanning from 14:10 of the first period until 17:51 of the second period.
"I thought Calgary was good in the neutral zone, didn't really give us much, didn't really have any odd-man rushes or second or third opportunities in the O-zone," Sillinger said. "It was one and done. They were blocking shots and getting the puck up. In the first couple periods there we didn't have our jam, have our pop, have our urgency that maybe we're used to or have had going the last couple of games."
Backlund appeared to score at 12:40 of the third period when he tipped Andersson's point shot, but the Blue Jackets successfully challenged that the Flames had entered the zone offside.
Kevin Bahl scored a power-play goal, a wrist shot from the point through traffic, to push it to 2-0 at 17:53, and Yegor Sharangovich scored into an empty net with 20 seconds remaining for the 3-0 final.
"Lots of emotions," Vladar said. "That one, you kind of don't really want to play hockey but you remember Johnny and how he always wanted to play hockey with a smile on. This one's for him. He was watching us for sure. This one goes to him."
