The Ducks stretched the lead to 2-0 at 14:07 of the second period when Lundestrom deflected a shot over the head of Luukkonen and across the goal line six seconds after an Anaheim power play ended.
"'Lundy' is probably one of the most reliable players. He really thinks like a coach on the ice," Cronin said. "We're all hoping we'll get a little more offense out of him because he does get some quality ice time, but I think that'll come. Tonight's goal was kind of a blue collar goal, he got in front of the net, but when he's on a line, he stabilizes whatever line he's on."
Ducks forward Frank Vatrano could not capitalize on two prime scoring chances that would have extended the lead to 3-0 late in the second period.
Vatrano has scored just two goals in 18 games after scoring an NHL career-high 37 last season.
"Last year was a breakthrough year, so the expectation that he's going to be a 30-plus goal scorer has been set," Cronin said. "I'm not worried about him scoring goals. ... I do believe that his shooting percentage will go up. It's really low right now, but the worst thing he could do is stop shooting the puck."
The Sabres scored twice in the final 1:23 of the second period to tie the score heading to the third.
Krebs pushed the puck across the goal line after it got behind Gibson following a save on Tuch's deflection to make it 2-1 at 18:37.
Zucker then got loose on a breakaway and scored for the second consecutive game to tie it 2-2 at 19:27.
"We ended up screening our goaltender on their first goal, but we came back hard in the second," Buffalo coach Lindy Ruff said. "I think you got to find ways to win those games, they’re hard to win but you got to give the group a lot of credit, we gained a lot of momentum there at the end of the second."
