Having two days to recover before its next game will help Team Russia physically after it opened the tournament by playing on consecutive days. Left wing Ivan Telegin twice struggled to get off the ice after blocking shots in the third period on Monday, but Znarok said he was "feeling well" on Tuesday.
Team Russia was also feeling much better psychologically after getting a victory. Russia has struggled recently in best-against-best tournaments, failing to win a medal in the past three Olympics, including as the host country in the 2014 Sochi Games.
So winning on Monday was big boost for its confidence.
"It was a good win for us," Team Russia center Evgeni Malkin said. "We feel so much better. We played against a great team of young stars. It's an unbelievable team, so fast, but now we look to the next game against Finland and we need to win again."
All four of Team Russia's goals on Monday came in a span of 6:14 in the second period. During a 10-minute surge, it exposed some weaknesses in Team North America's defense and took advantage of some shaky goaltending by Matt Murray.
Team Russia generated more scoring chances during that stretch than it did in the entire game against Team Sweden.
"I think we were pressuring their 'D' a little bit into making mistakes and we got a screen in front of Murray and more shots," said right wing Vladislav Namestnikov, whose goal 9:29 into the second period tied the game at 1-1.
Namestnikov was a healthy scratch for the loss to Team Sweden, but played in place of Vadim Shipachyov on Monday. That lineup change paid off, as did Znarok's tinkering with the line combinations.
Right wing Vladimir Tarasenko moved up to the first line with Alex Ovechkin and Pavel Datsyuk and Kucherov slotted down to the second line with Nikolay Kulemin and Malkin. In addition, Evgeny Kuznetsov moved up to center Artemi Panarin and Evgeny Dadonov on the third line and Namestnikov took Kuznetsov's former spot at right wing on the fourth line with Telegin and Artem Anisimov.
Tarasenko, Kucherov, Kuznetsov and Namestnikov all scored goals.
