Despite his dominance in extra time, Marchand said he's not expecting everything to work in his favor during every 3-on-3 opportunity.
"You get that confidence a bit, but it all has to go right," said Marchand. "Guys have to make plays and you have to start with the puck a lot of times which we were able to get it back tonight. You need a lot of things to go right, but sometimes you benefit from certain plays, sometimes you don't.
"This year I've played with a lot guys that can make plays and I've benefitted from that."
For Bruins coach Bruce Cassidy, Marchand's goal was business as usual. In his last 13 games - 12 of which came without Bergeron alongside - Boston's No. 1 left winger has collected 22 points (9 goals, 13 assists), the fifth highest total in the league during that span.
"At some point, when he's out there and you get puck possession, he'll probably generate something. He's really been able to finish," said Cassidy. "Overtime specifically and especially this month, he's sure come through for us. He's an elite player. We expect him to get his looks every night because he's hard on the puck and a competitor.
"Doesn't surprise me. Again, he was hard on it tonight…their line was very good again tonight."
