The Sabres captain wants to help them and their supporters out of those dark times.
Buffalo went 2,081 days without a winning record, a streak of futility that came to an end with a 4-2 victory against the Vegas Golden Knights at KeyBank Center on Monday.
Eichel, who scored two goals in the win, knows the season is three games young, but he said every positive step must be embraced by a team that has not made the Stanley Cup Playoffs since 2010-11.

"I think we're playing with a bit more confidence," Eichel said. "The things we can control is compete and attitude."
The Sabres had a 2-1-0 record Jan. 24, 2013, after a 6-3 loss to the Carolina Hurricanes. They lost 3-1 at Carolina the following night in the second game of a home-and-home and had not achieved a winning record again before improving to 2-1-0 Monday.
Eichel was a 16-year-old kid attending high school in Ann Arbor, Michigan, at the time. He has grown up a lot over the past five-plus years. Now in his fourth NHL season after being selected with the No. 2 pick in the 2015 NHL Draft, he's seeing signs that the Sabres are too.
"I think we're coming together as a group," said Eichel, who was named captain Oct. 3. "We're not a finished product, by any means, but I think you can see the togetherness we're starting to play with. There are still a lot of things we can get better at and clean up, but there are a few things you can control, and one of them is your compete level. I thought we competed the past few games.
"At times I've thought we shot ourselves in the foot with turnovers. … Still, when you are winning games and you are not playing your best, it's a good sign."
