The most recent collapse happened in 2015, when the Capitals had a 3-1 series lead in the Eastern Conference Second Round but lost in seven games to the New York Rangers.
This year, Washington had a 3-0 lead in this first-round series against the Philadelphia Flyers before losing Games 4 and 5. Although the Capitals have to go back to Philadelphia for Game 6, they don't believe history will repeat itself.
"Everybody talks about, 'The past, the past, the past," Washington coach Barry Trotz said Saturday. "The only pressure we will have is on ourselves. We have to go into Philadelphia and we have to play really well and get a win there. If we don't accomplish that, then we will go to Game 7. Keep playing that way, and it will turn."
Forward Justin Williams said the Capitals have to play their game.
"If you don't have your confidence, you don't have your swagger and you're just someone who's waiting for something bad to happen," Williams said. "We want to make something good happen."
Washington lost Game 5 at Verizon Center on Friday 2-0 despite outshooting Philadelphia 44-11. It was the fewest shots in Flyers history, regular season or playoffs, but goalie Michal Neuvirth set Flyers records for most saves in a playoff shutout win and most saves in a postseason regulation victory.
In 2010, the Flyers came back to win their second-round series against the Boston Bruins after falling behind 3-0. Captain Claude Giroux, the only player remaining from that team, doesn't like the comparison.
"It's really hard to compare to 2010," Giroux said. "The way we work and all year we're battling to make the playoffs and we're playing playoff hockey for about three months there, to be in the position we are, we're starting to enjoy it. It's playoff hockey. It's a lot of fun."
