Despite his refusal to be labelled a hero, that's exactly what Oshie was (since a hero is literally defined as the principal character in a story, and Oshie became precisely that when Team USA decided to go to him again and again once the game reached the shootout). Oshie scored four times on six shots, propelling the US to a victory, and causing minor quakes in gathering spots all over the country.
After the game, we learned that Oshie's shootout prowess played a major role in his selection to Team USA, where international hockey rules allow players to be used repeatedly (perhaps in an effort to rob the Marek Maliks of the world of their moment).
It was a smart choice. Oshie isn't known for highlight-reel shootout moves, particularly, like Team USA teammate Patrick Kane, for instance, but while he doesn't always make Sportscenter, he usually makes good. He's near automatic, at 25-for-46 in his pro career.
How does he do it? He's incredible at adapting to what goaltenders give him, for one thing. Watching a number of Oshie's shootout moves back-to-back, you'll notice that he approaches the goal pretty much the same way every time: carefully, slowly, and with his head up. After that, his decisions are based on the goalie. You can watch all of his shootout attempts versus Russia here. But we're going to go a little further back.
He's been doing basically the same thing since day one. Here's his first-ever NHL shootout attempt, from a 2009 game versus the Chicago Blackhawks:
