Duchene found the opening because Bruins forward Noel Acciari sagged low and forward Sean Kuraly mistakenly pushed up high with his stick to try to take away Jones' pass to Atkinson. The middle was wide open.
"One of the best things a power play can do is take advantage of mistakes," said Columbus assistant Brad Larsen, who runs the power play. "We talk about it all the time, make your reads. Kuraly got caught out of position and we took advantage of it. It's what good power plays do."
They also adjust when necessary, which is what the Blue Jackets did after going 0-for-4 in Game 1 against the Bruins.
Jones replaced defenseman Zach Werenski up top on the first power-play unit, a subtle move that changed Columbus' mentality and direction.
Jones, who shoots right-handed, is more of a shooter, especially if the one-timer is available.
"If I see a shot lane I'm going to take it," Jones said.
Werenski, who shoots left-handed, but in Game 1 looked to be more comfortable in settling the puck, holding it and then moving it with either a pass or a shot.
With Jones at the blue line, the Bruins had to respect his shot at a time when they also wanted to take away Panarin's one-timer. It led to some indecision and mistakes.
The Bruins didn't cover either Jones or Panarin on Panarin's power-play goal 1:03 into the second period of Game 2. The defenseman set up the forward for a game-tying one-timer.
