Penguins have come back before

Via: Beaver County Times

'The Penguins took out New Jersey after trailing 3-2 in the Patrick Division Semifinals in 1991 and overcame a 3-1 deficit the following year against Washington in the Patrick semis. They also overcame a 3-1 Capitals' lead in the 1995 Eastern Conference Quarterfinals. They know the drill, and all three said they plan to leave everything they have on the ice tonight.'
