DeBoer wasn't even Sharks coach when he first saw Donskoi, playing for Finland at the 2015 IIHF World Championship. But he noticed him.
Then, as San Jose coach, the first place DeBoer saw him was at rookie camp in August. He noticed him again, more than he planned on noticing him, in fact.
"I didn't know a lot about him as a player," DeBoer said. "All I knew is he had a good year in the Finnish league. An NHL coach automatically says, 'OK, he'll help our American League team and we'll see how he does.' He just kept knocking on the door and wouldn't take no for an answer."
It all paid off Friday when the Sharks finally put down a Kings team that tormented them with a comeback from San Jose's 3-0 series lead in 2014 and a Game 7 victory in 2013.
The Sharks were able to survive their second-period meltdown, which looked strikingly similar to a third-period meltdown two nights earlier that almost cost them Game 4, because they could rely on more players than in the past.
"The depth allowed us to get through," DeBoer said. "I think there was a reason they weren't able to get over a hump like this in the past, and I think that is the reason because with our group right now, we have contributing depth we can play."
