"We can't chase games," Williams said. "Chase, and chase and chase; it's exhausting. Our urgency from the start of the game has to be better. It's blatantly honest and it's pretty obvious."
Carolina (35-24-5) trails the Columbus Blue Jackets by one point for the second wild card into the Stanley Cup Playoffs from the Eastern Conference.
"We've done it all year, coming back, but it's just why we weren't really ready from the start tonight was a little frustrating," Hurricanes coach Rod Brind'Amour said.
Carolina forward Sebastian Aho was held without a point for the first time in 15 games. He had 21 points (12 goals, nine assists) during his 14-game streak, which was the third longest in the NHL this season (Jack Eichel, Buffalo Sabres, 17 games; Patrick Kane, Chicago Blackhawks, 15 games).
"You're not going to play great every night," Brind'Amour said of Aho. "And give their team credit, they were on it at the start, and that had a lot to do with making him not be a factor. But he's world class, he means the world to us."
Phillip Danault and Brendan Gallagher each had a goal and an assist for the Canadiens (30-28-9), and linemate Tomas Tatar had three assists.
