Vegas coach Peter DeBoer predicted Wednesday it would be a rough ride for Eichel.
"The first 20 minutes, they owned the emotion and the energy and that's not surprising," DeBoer said. "I think you had a crowd, a team, a city that was emotionally invested in this game."
DeBoer said it's good to get the occasion over with, both for Eichel and the Golden Knights.
"You've got a whole city invested here in him and what happened," he said. "Now it's in the rearview mirror. Hopefully we don't have to deal with that again.
"I think there's no doubt it was weighing on him, like it would anybody. It's human nature."
Fans booed Eichel throughout warmups, holding signs that said, "Thanks for nothing Jack. Boo!' and "Eichel #9. I'm not mad, I'm disappointed."
They also jeered when a tribute video appeared on the scoreboard at center ice during the first television timeout early in the first period. Some of those turned to cheers when a number of children he had spent time with at Roswell Park Cancer Institute in Buffalo appeared on the screen thanking him for what he'd done to help them.
"I was trying not to watch it," Eichel said. "I feel like I'll look at it another time. I didn't want to get emotional and start thinking about stuff like that, especially when you start involving some of the kids and some of the things I did in the community here. I think that hits home.
"I did appreciate the tribute though."
Eichel had two shots and was minus-1 in 17:50 of ice time. He was overshadowed by Krebs and Tuch, who each scored a goal against his former team.
"You can talk about the boos and stuff like that, but honestly, we heard a lot of cheers, we heard a lot of Buffalo chants," Tuch said. "The crowd was on our side, they really were and it was electric tonight. It was a phenomenal feeling, and to get a win in front of that big of a crowd is something that really goes a long way.
"We want to keep feeding off that energy and build momentum and keep that going, so we hope to see all those fans back in the building here soon."
On this night, KeyBank Center had the electricity and vibe of a Stanley Cup Playoff game. Tuch and his teammates won't soon forget it.
Eichel, on the other hand, certainly is going to try.
