Hall did a bit of that on his own, setting the stage for Marchand's overtime heroics when he tied the game with a greasy net-front tally in the closing minutes. With Boston trailing, 3-2, Hall jammed away at a loose puck in the crease and, eventually, whacked it by Washington goalie Craig Anderson to knot things up with just 2:49 to go in regulation.
"That's something that our group is so good about," said Marchand. "We don't panic throughout games. We have so much character in our room. You can sense it all the way through the bench during the timeouts and in the room. There's a sense of calm when things aren't going our way.
"We have Tuukka [Rask] back there to kind of bail us out in situations like that, gives us a minute to find our game. That's what happened. At this time of the year, it's about competing and that's what we did tonight.
"We found our game there, especially against a tough team. They're really good. You're not gonna dominate a team like that. It's gonna be back and forth, especially in their building. They were loud tonight, and they got some momentum off of that."
But Marchand wasted no time silencing the rowdy Capital One Arena crowd in the opening seconds of overtime. David Krejci started the winning sequence when he settled a puck at the right point and zipped a pass across the blue line to Matt Grzlecyk.
The blue liner quickly delivered a cross-ice feed to Marchand, who ripped home a one-timer from the right-wing circle to end it just 39 seconds in. Per NHL Stats, it was the fastest goal to start a postseason overtime in Bruins history, surpassing Bobby Orr's legendary Stanley Cup winner in Game 4 of the 1970 Stanley Cup Final (40 seconds).
