The poke check provided an emotional spark for Carolina, which lost 3-0 at the Florida Panthers on Wednesday.
"It was a special play by 'Kotchie,'" Svechnikov said. "I feel like he gives you more confidence and you want to play for him as well, especially since that was his first game this season."
Staal scored on the backhand to make it 4-1 with one second left in the second.
"I thought we got off to a good start, but giving up late-period goals hurts," McDavid said. "We gave up one in the first, we gave up one in the second, and playing catch-up against a team like this is not easy. It takes a lot of energy to play catch-up. Obviously it's not easy on anyone and we have to do a better job of not letting that happen."
