After starting the year 1-6 in the extra session, the Bruins have now won three straight overtime games over the last two weeks, with two of the winners coming from Marchand.
"Having the puck helps," said Cassidy. "I think we did a good job puck possession. Listen, it was one of those games that we had the puck around their net so much that I can't remember if they had a chance in overtime right now…I think guys are understanding the value of puck possession, maybe more now that we've dug it out of our net earlier in the year in these overtimes, so they're taking it to heart."
The overtime winner was made possible by Jake DeBrusk's tying tally with 2:45 to play in regulation. Following a frustrating night on the power play, which started 0 for 5, Boston finally broke through on its final man advantage of the contest.
Nick Holden took a Torey Krug feed and delivered a slap pass to DeBrusk in the slot, where the rookie tipped it by Niemi to knot the game at 1.
"We had a handful of power plays there that we got some decent looks just weren't connecting," said DeBrusk. "I think it was just a matter of timing in the game, I think it was just late in the game we wanted to get pucks to the net.
"I think one of their guys accidentally dropped their stick or had a stick broken, you've got to take advantage of that and obviously it was nice to cash in."
