"You look around the room, it's been a while since we've been able to put the smiles on our faces," Montreal forward Brendan Gallagher said. "There have been games where obviously we didn't deserve to win. There have been a couple where we fought pretty hard and just didn't get the result. So, it's nice for this group to have a win. And regardless of what happens all year, this is the feeling that you play for."
