It’s official: the first round of the Stanley Cup Playoffs will feature a renewal of the Battle of Pennsylvania.

In glorifying the history between these two cross-state rivals, many look back to the 2012 first round series between them. The rivalry was a joy for all involved, whether you had a side in the fight or were a neutral observer.

But that series was not the most recent playoff meeting between the Penguins and Flyers.

Six years after that electric 2012 series, they clashed in the first round again in what is now a pretty forgotten chapter in the Battle of Pennsylvania.

The Penguins, the first back-to-back Stanley Cup Champions in the salary cap era, were embarking on a three-peat bid in 2018. They set themselves up well with 47-29-6 record, good for an even 100 points and a second place finish in the Metropolitan Division.

Nipping at their heels, however, were the Flyers. Finishing at 42-26-14, Philadelphia finished just two points behind the Penguins, snagging third place in a division that sent five teams to the tournament that year.

With home ice advantage, a 4-0 record over the Flyers in the regular season, and their immense recent postseason success, the Penguins were the heavy favorite heading into this series.
