Matt Murray
What Murray did in 2016 (15-6, 2.08 GAA, .923 save percentage) was remarkable because he had Marc-Andre Fleury, a Stanley Cup winner, lurking over his shoulder. Murray replaced Jeff Zatkoff as the Penguins starter in Game 3 of the first round against the New York Rangers. Murray allowed four goals on 89 shots (.955 save percentage) to help the Penguins win the series in five games. He got through a six-game series against the Washington Capitals, allowing 11 goals in the final five games after giving up four in a Game 1 loss. Fleury, who had been injured at the start of the playoffs, relieved him in Game 4 of the third round against the Tampa Bay Lightning and Murray was benched for Game 5. He wasn't rattled. The Penguins, down 3-2 in the series, needed the rookie again. He delivered, allowing three goals on 47 shots to win Games 6 and 7. He was equally as good in the Cup Final, allowing 11 goals in six games against the San Jose Sharks.
