Stone scored 61 points (21 goals, 40 assists) in the regular season, tied for 10th in the NHL in scoring. He had eight points (five goals, three assists) in 13 games in the first two rounds of the playoffs, then no points in six games against the Canadiens.
"That can't happen," said Stone, who said he was not playing hurt. "I'm the captain of this team, the leader of this team. I take a lot of responsibility for what just occurred, but if I can, I guess, take anything, I'll have to see what went wrong over the summer. …
"I'm excited to learn from mistakes and try and build this team to a Stanley Cup winner, not just a contender."
Told Stone had been critical of himself, coach Peter DeBoer said, "Well, I'm not surprised he's taking that on himself, but that's not a load he needs to carry and definitely not alone."
Smith and Max Pacioretty each had three points (one goal, two assists) in the series. Alex Tuch had two assists, Jonathan Marchessault one. Chandler Stephenson missed three games with an upper-body injury and had one assist in three games.
Goalie Marc-Andre Fleury misplayed the puck late in the third period of Game 3, leading to the tying goal with 1:55 to go. Instead of taking the series lead, Vegas went on to lose 3-2 in overtime and fall behind 2-1.
"When you get to this point, the teams that win find another level," DeBoer said. "They don't sag. We didn't find another level, and they did.
"I thought they were opportunistic. They owned the key moments of the series. When they got a chance, they stuck it in the net. When they needed a big save, they got a big save. They won the overtime battle. They won the special teams battle. If you're losing those areas of the game, you're putting yourself in a tough spot."
DeBoer said he felt the Golden Knights made progress this season, but everything is on the table for the future.
"There's another door we've got to find a way to barge through at this time of year," DeBoer said, "and I think everybody's got to look in the mirror, obviously coaches included."
The Golden Knights have come close to the Stanley Cup three times in four seasons. Now they have to find a way to go all the way.
"I think it's just getting over that hump," Stone said. "Teams go through this. We've got to continue to learn and grow this organization. Four years in, we've had success, but going into Year 5, it's again, it's the expectation is to win the Stanley Cup."
