LAS VEGAS – Gerard Gallant and the Vegas Golden Knights still think Tom Wilson's third-period hit on Jonathan Marchessault in the Stanley Cup Final opener was probably a bit dirty.

The coach also believes it sparked his team's comeback victory.

While he wasn't happy to hear Wilson will face no discipline from the NHL, Gallant is hoping his team will remember the hit – and how they played right after it – when they attempt to take a 2-0 series lead on the Washington Capitals tonight on the Strip.

“The good thing about the hit is it really woke our team up,” Gallant said Tuesday. “I think it was a 4-4 game?”

Indeed, two novice Stanley Cup finalists were deep into an entertainingly ramshackle opener, but the Knights took charge after that fateful collision left Marchessault sprawled on the ice. Vegas quickly got Tomas Nosek's go-ahead goal, eventually won 6-4.

The focused aggression necessary to be a successful postseason team is a delicate concoction. The Golden Knights and Caps both had it during the conference playoffs, but they both admit it got away from them in Game 1.

“I think both teams can be better,” Washington coach Barry Trotz said. “It was a pretty sloppy game.”

After one game to get used to the sky-high stakes of the last round of this tournament, both teams intend to channel their nervous energy more constructively in the future.

“There's obviously nerves,” Washington's Jay Beagle said. “I'm not surprised at anything anymore, but in the Stanley Cup Final, usually it's 2-1 or 1-0, not (6-4). But you don't know what to expect from a team that you don't know that much. Now we've got to know them a little bit more.”

The mistakes that worry coaches also lead to exciting hockey, and the opener was thoroughly entertaining. The teams combined for a Final-record four lead changes in the highest-scoring opener in eight years for this final round.

Wilson, who served a three-game suspension in the second round for breaking the jaw of Pittsburgh's Zach Aston-Reese, and the Capitals still insist the hard-charging forward did nothing wrong when he leveled the Golden Knights' top playoff scorer.

“It's within the rules,” Wilson said after practice at T-Mobile Arena. “It's a clean hit. I don't know why it got so much media attention, to be honest.”
