“I thought our compete and our kind of swagger was way better,” Chicago coach Jeff Blashill. “That's more the standard that we want to play with. Obviously, you're going to make mistakes, and you want to learn and grow, and that's what we'll focus on.”
Dahlin tied it 3-3 at 6:10 of the third period for the Sabres, taking a pass from Peyton Krebs at the right hashmark off the rush and beating Knight with a snap shot stick side.
Donato gave Chicago a 1-0 lead at 7:59 of the first period. Alex Vlasic carried the puck down the left side to the net before sending a centering pass to Donato in the slot.
Bertuzzi finished off a tic-tac-toe passing play to make it 2-0 at 11:24. Anton Frondell drew Luukkonen to him as he took a feed from Teuvo Teravainen in front and quickly passed it to Bertuzzi, who put it into the open net from the left side.
Jack Quinn’s wrist shot from above the slot went top right corner to cut it to 2-1 at 16:24.
“I think he could have had three tonight easy,” Sabres coach Lindy Ruff said of the forward, who has scored in each of Buffalo’s first two games. “He’s really skating well. Talked a lot about last year, he had that segment where he really was snakebit. Just couldn't get could buy one, but for him to have him start going in right now, I think it’s a great sign for us.”
