Giveaways plagued them.
"We had a lot of unforced turnovers [Sunday] that we need to correct," Vigneault said.
The Rangers had no forecheck because the majority of their dump-ins went straight to Canadiens goalie Carey Price, who is no stranger to playing the puck and playing it well.
"If he gets it, he's going to get it out of there and it's going to be tough to forecheck," center Derek Stepan said.
Tape-to-tape passes went off the tape and out of reach. They had no transition game, their bread and butter all season. They had no pressure, which is why they had 12 shots on goal through two periods, six in the first and six in the second.
And their power play is simply being eaten up by Montreal's penalty kill. It went 0-for-3 with three shots on goal and is 0-for-10 with 11 shots on goal in the series.
"Offensively, we need to do more, create more," Rangers forward J.T. Miller said. "I'm not saying low-percentage plays and high-risk across the middle of the ice. I'm saying we need to establish a forecheck and keep the puck and make them defend. We have not made them defend enough to this point."
Although it may not be fair to single him out, a perfect example is center Mika Zibanejad, who admitted Monday that he hasn't been difficult to defend.
"When I play my best game I'm keeping the puck, I'm holding onto it, I'm dragging them to me to take a play, and I'm not doing that right now," Zibanejad said. "Right now, it's just gripping the stick a little too hard, almost more afraid of making mistakes then willing to make a play."
Zibanejad said ideally when he gets the puck in Game 4, he's going to hold on to it, try to draw defenders to him, basically bet on his skill.
"Personally I'd rather make a mistake when I'm trying, when I'm skating with the puck and trying to make a play than a mistake when I'm passive and I get the puck stripped from me," Zibanejad said. "We have enough skilled guys here that we can make that play. You have to take a chance at some point."
That goes to a theme Stepan was harping on Monday, working hard vs. working smart. The former can help a team stay in the game even if it's getting outplayed, like the Rangers did in Game 3. The latter is the difference in winning the game.
