Pittsburgh is 9-3 all-time in playoff series under head coach Mike Sullivan. His nine playoff series victories are the most in franchise history, and his 39 playoff wins are four shy of tying Dan Bylsma's team record (43).
The 2021 Stanley Cup Playoffs marks the 15th consecutive playoff appearance for the Penguins, which is an active franchise record. It is also the longest active playoff appearance streak among major North-American professional sports leagues.
Heading into this series, the Penguins have advanced to at least the second round of the playoffs eight times in the 13 playoff runs they've had with Sidney Crosby and Evgeni Malkin in the lineup. In five of the 13 runs, Pittsburgh has gone to at least the Conference Final.
The Penguins have eight players on their postseason roster looking to make their NHL playoff debut - forwards Evan Rodrigues and Radim Zohorna, defensemen Mark Friedman and Juuso Riikola, and goaltenders Casey DeSmith, Alex D'Orio, Maxime Lagace and Emil Larmi.
Assistant coach Todd Reirden has coached a division-winning club as either head or assistant coach for six-consecutive seasons (PIT - 2020-21; WSH - 2015-20).
