"You've just got to worry about stopping the next one," he said. "It doesn't matter when a goal goes in. You can't take it back. Just worry about the next one."

It's a goaltender's job to have a short memory, to not let past goals affect present and future performance. Murray, 23, has done that well during his three NHL seasons, and did it again when he made 32 saves in the Penguins' 3-2 comeback win against the Capitals that gave Pittsburgh a 1-0 lead in the best-of-7 series.
Game 2 is at Capital One Arena on Sunday (3 p.m. ET; NBC, CBC, TVAS).
Murray has saved his best performances for the Stanley Cup Playoffs. He is 5-2 with a 2.17 goals-against average and .917 save percentage in seven games, and 27-11 with a 1.99 GAA and .926 save percentage in 39 career postseason games. He's been the starting goaltender when the Penguins won the Stanley Cup in 2016 and 2017.
Mike Sullivan, who has coached Murray with the Penguins and Wilkes-Barre/Scranton of the American Hockey League, said Murray always has shown that calm.
