Huberdeau had no points and was minus-2 in a 6-1 loss to the Toronto Maple Leafs on Thursday.
"I really challenged our leadership group to step up after what happened against Toronto, and he was a big part of that," Boughner said.
Dadonov played on the first line with Huberdeau and Barkov, taking Hoffman's place
"We have so much talent that it is great to play on either of our top two lines," said Hoffman, who plays on the first power-play unit. "Obviously, everyone wants to play with [Huberdeau] and [Barkov], but you don't change lines when things are going well, and those three have been great."
Vanek made it 2-1 at 10:00 of the second period, stealing the puck from Jared McCann behind the net and bringing it in front.
"I saw a little opening, so I just wanted to take it hard to the front of the net," Vanek said. "It worked out, but this was another frustrating loss. Obviously, we need to score more. It takes us 10-12 chances to get something."
